How to Create a Shared Vacation Calendar in Google Workspace
A shared vacation calendar in Google Workspace is one of those problems that every company has and that is surprisingly still not solved out of the box. You'd think Google would have a native "team vacations" view — they don't. Important to know: Google Calendar has a dedicated "Out of Office" event type — selectable in the event type tabs — that auto-declines meetings and shows your status across Workspace. Most people never use it because they just create a regular
Ship Your First AI Agent: How to Make LLMs Do Real Work in Your Product
The era when devices are controlled just by thought is almost here. Until then, chat 💬 beats menus and forms as the way to interact with systems — and each other. I recently embedded an AI agent into Jinna, a free invoicing tool. By the way you can log in and create beautiful✨ invoices there, for free! It feels like magic: Ask an AI agent for an invoice, and it creates one. Understands complex requests. Resolves ambiguity. Performs
Why You Should Build on Cloudflare by Default
For the past five years, Cloudflare has been my default infrastructure choice for nearly everything I build. I might be biased, but I genuinely believe Cloudflare gives you the most flexible, robust, easy-to-build, low-maintenance infrastructure — for FREE, until you finally make it. When DataUnlocker suddenly had to handle 50 million proxy requests per day after a major customer onboarded, I wasn't scrambling. No emergency scaling
Announcing AfterPack — JavaScript Obfuscation for the AI Era
Today I'm launching AfterPack — a Rust-based JavaScript obfuscator designed for the AI era. The waitlist is now open. Why I Built This I've spent years protecting web assets through DataUnlocker, watching how the landscape of code protection has fundamentally shifted. The rise of LLMs like GPT-4 and Claude changed everything — these models c
Google Deleted 10 Years of My Location History
I love Google. I worked at Google. It was my childhood dream to work there, and I made it happen. So what I'm about to tell you isn't coming from a place of hate — it's coming from a place of genuine disappointment. Google deleted 10 years of my location history. Not intentionally, but that doesn't make it any better. The Beginning: 2015 It all started back in 2015 when \[Google introduced Location History]\(https://maps.googleblog.com/2015/07/your-timeline-revi
Christmas Trip to Madeira
Christmas on a volcanic island in the Atlantic - Madeira delivered exactly the dramatic scenery I was hoping for. Madeira is an autonomous region of Portugal, sitting 520 km off the coast of Morocco. With a population of around 250,000, most concentrated in the capital Funchal, the island is essentially a giant volcanic mountain rising from the ocean. The terrain is incredibly steep, with deep ravines and cliffs dropping hundreds of meters to the sea. Fun fact: the island's highest point, Pico
Speaking at "AI Просмажка" about AI — a sold-out panel discussion
I was invited by my friends to speak at AI Просмажка — a panel discussion organized by the VUS (Великий Український Стартовер) community in Warsaw. The format was a "roast" of AI: four speakers with different backgrounds critically examining the hottest topics around artificial intelligence, followed by networking at the bar. The event sold out, which was a nice surprise for a niche topic in a city where the Ukrainian tech commu
Table Games in Krakow - Almost 2 Years of Board Gaming with IT Community
For almost two years I organized bi-weekly table games in Krakow. The first game was announced on January 14, 2024, and the last one was held on August 3, 2025. In total, we played around 40 sessions with an average of 15–20 people attending. At peak times, we had close to 30 people gathering in one place. The Format The workflow was straightforward: we'd gather at 4pm, start with 1–2 hours of a warmup game that works well with large groups - usually Codenames projected on the big screen.
DataUnlocker 2.0 is generally available
After more than two years of steady work — with many twists, lessons, and iterations — I’m happy to share that DataUnlocker 2.0 is now live! What is DataUnlocker? In simple terms, DataUnlocker helps websites recover visibility into the user actions that are often lost due to ad blockers and privacy tools. Today, many businesses rely on tools like Google Analytics or Facebook Pixel to understand what users are doing on their site, track revenue, or measure conversions from their market
Interview on Founder Wisdom Podcast
I was invited by Charles Cormier to appear on the Founder Wisdom podcast, where we had a deep conversation about my journey as a technical founder, bootstrapping DataUnlocker, and my perspectives on the crypto industry. What We Discussed The conversation covered quite a few topics: DataUnlocker and the Analytics Problem. I explained how websites lose 20–50% of their user data because ad blockers categorize analytics scripts as
A day in Kosovo
Kosovo is one of the "youngest" countries in Europe, having declared its independence in 2008 (fact: Ukraine has not recognized Kosovo's independence). Its capital, Pristina, is known for its vibrant street life and unique blend of cultures. I was especially impressed to see a very big Ukrainian flag displayed on the central square, a symbol of solidarity that stood out during my visit. The main reason for my tr
A few days in North Macedonia
North Macedonia! If you want to name one country that renamed itself in the past years, that's North Macedonia. After the visit I continued my journey to Greece's Macedonia - the reason for the name change. Both Greece and North Macedonia wanted to claim the name "Macedonia" - and in February 2019 it was renamed to "North". The country itself
A weekend in Belgrade, Serbia
Visiting Serbia was part of my ongoing journey to visit every country in Europe — after this trip, only North Macedonia and Kosovo remain on my list. My time in Belgrade was short, but it left a strong impression. The city itself is quite compact compared to other European capitals; you can easily walk across the center in under an hour. During my stay, I noticed groups of people regularly crossing one of the mai
Open a 0% Tax Company with Estonian e-Residency Card
The Estonian e-Residency card enables creating a remote digital business with significant advantages. Think of it like a gym membership in another city - full access to business infrastructure remotely, but no key to sleep in the building. How to Get Started The process is straightforward: Apply online - fill out the application form Pay the state fee (~100-120 EUR) Wait for approval (~3-4 we
A week in Barbados
Who in Europe even thinks of Barbados as a destination? Barbados was a result of the spontaneous decision to go somewhere "very far" from Poland. Indeed, it was over 14 hours of flights and 3 layovers! The island was nice with great nature. Having monkeys just at your villa is so wonderful. Some nature sights and beaches are also worth it all. Two things I didn't like about Barbados is food and the stylishness of places on it. Food (especially vegeta
Vatican and the Sistine Chapel
My second visit to Vatican City, and this time I came prepared. Unlike my first rushed trip in 2020, I actually took my time to appreciate the Sistine Chapel properly - Michelangelo's ceiling is one of those things that photos simply cannot capture. Standing there, neck craned upward, I finally understood what all the fuss was about. Vatican City remains t
A few days in Andorra
Andorra became my 68th country, and what a unique one it is. This tiny principality tucked between France and Spain in the Pyrenees mountains is technically a co-principality - ruled jointly by the President of France and the Bishop of Urgell. With just 77,000 residents and 468 square kilometers, it's one of Europe's microstates that somehow maintains its independence since the 13th century. What I Experience
Dr. Nikita Savchenko – Officially a PhD!
On October 30, 2024, I defended my PhD work at the Institute for Information Recording of the National Academy of Sciences of Ukraine. This milestone marked the culmination of years of research and dedication to the field of Information Technology, specifically within Computer Science. My thesis, titled "A Method of Decentralizing Knowledge Bases for Decision Support Systems", explored innovative ways to ease blockchain applications adoption and in particular bring decentralization to knowledg
Trip to Romania
Romania - home to Dracula's legend, the famous Transfăgărășan highway, and some of Europe's most underrated natural beauty. With a population of around 19 million, Romania offers a fascinating mix of medieval history, Carpathian wilderness, and a surprisingly affordable travel experience. Fun fact: Romania has one of Europe's largest populations of brown bears - around 6,000 of them roa
Product Owner at Cyber.fund - Building Y App
I joined Cyber.fund as a Product Owner to help bootstrap Y App (Y Nation) - a next-generation decentralized identity (DID), wallet, and DeFi application. Working in a small team of founders (CEO, PM, CTO, Designer), I was responsible for: Assembling product requirements and user stories Designing user flows and conducting UX research Benchmarking competitors and conducting market research Shaping the product vision for the decentralized identity space The projec
My First Rave - DJ'ing from an iPad with 50+ People
I've organized events before - back in student years I ran Google Hash Code gatherings for around 100 people. But this was different. This was my first rave, and I was the one behind the decks. Well, behind the iPad. The idea had been brewing for a while: find the most isolated spot possible near Krakow, set up proper sound equipment, and throw an outdoor party for 50+ friends. No noise complaints, no distractions, just us and the music under the night sky. What Made It Special The locati
Car trip to Slovenia
Slovenia turned out to be one of those countries that exceeded every expectation. We drove across the entire country over three days, and I genuinely loved everything about it - the alpine scenery, the pristine lakes, the efficient infrastructure, and the surprisingly affordable prices. With just 2 million people and a territory slightly smaller than New Jersey, Slovenia packs an incredible variety of landscapes. In one day you can drive from Mediterra
A lovely evening at San Marino
San Marino is one of those places that makes you realize how arbitrary country borders can be. This microstate of just 34,000 people sits entirely on a mountain surrounded by Italy, claiming to be the world's oldest surviving republic - founded in 301 AD by a stonecutter fleeing religious persecution. The entire country is essentially one mountain, Monte Titano, with the historic center perched at the ver
It's Malta time
My second time in Malta, and this time I had a whole week to explore - plus a wonderful excuse: my friend's wedding! Having already seen the highlights during my 2020 visit, I could now dig deeper into what makes this archipelago so special. Malta is a fascinating mix of influences - Phoenician, Roman, Arab, Norman, Knights of St. John, British, and finally independent since 1964. With just 500,000 people crammed into 316 square kilometers, it's one of th
Level up in finance: completing an advanced trading course
So I decided to get a deep understanding of a few things: How markets work (all 3: Crypto, Forex and Indexes) How traders live and whether the life of a trader is indeed a breeze How to perform analysis of markets and what to watch for Success and failure stories Merciless market rules I've got all the answers by passing the most fully-packed "Supercharged" course by Cryptology - an awesome Ukrainian growing crypto community. Trading is definitely not
Maastricht, Netherlands
Half a day in Maastricht was enough to make me fall in love with the Netherlands for one thing I already love: cycling. The biking infrastructure here is legendary, and seeing it in person finally made me understand why the Dutch are considered the world leaders in urban cycling. The Netherlands is one of the most densely populated countries in Europe, with 17 million people in a territory half the size of
A day in Luxembourg
Luxembourg City was gray and overcast on the day of my visit, but even the weather couldn't diminish the impression. This tiny country has created one of the wealthiest economies per capita in the world, and the capital city reflects that prosperity while somehow avoiding feeling soulless. Luxembourg is a genuine oddity - a Grand Duchy of 650,0
Quick trip to Belgium
Short weekend-style trips are my favorites when it comes to Europe, and Belgium is perfect for exactly this kind of visit. Brussels made an immediate impression - a city living its full life, buzzing with activity, somehow managing to be both a major EU capital and a genuinely livable place. Belgium is a fascinating country precisely because it's barely a country at all. With 11.5 million people split between Du
A few days in Albania
My second visit to Albania, this time in the off-season. We came specifically to explore the mountains around Krujë, a historic town perched on the slopes of Mount Sarisalltik. Having seen the coast during my 2021 trip, I wanted to experience a different side of this underrated country. Albania has transformed dramatically since the fall of communism in 1991. With 2.8 million people and a turbulent 20th-century history (it was the most isolated country in Europe under Enver Hoxha's dictatorshi
Trip to Ireland
Ireland became my 67th country, and we packed a lot into just four days. A road trip with friends through the Irish countryside in early December - dramatic weather, empty roads, and some of the most stunning coastal scenery I've seen anywhere. Ireland is a country of contrasts: 5 million people on an island roughly the size of South Carolina, split between the Republic and Northern Ireland. It has transformed from one of Europe's poorest co
Trip to Morocco
A spontaneous winter escape to Morocco! When I found $100 round-trip flights from Katowice, Poland, it was impossible to say no. Morocco has a population of around 37 million and sits at the crossroads of Africa and Europe, with a rich blend of Arab, Berber, and French influences. Fun fact: Morocco is one of the few places in the world where you can see goats climbing argan trees to eat their fruit - and yes, that was the main highlight of my trip!
Trip to Iceland
One of the most wanted destinations is done! That was a huge experience. Iceland is a country of dramatic contrasts - with just 380,000 people spread across an island the size of Kentucky, it's one of Europe's most sparsely populated nations. Sitting on the Mid-Atlantic Ridge where tectonic plates diverge, the landscape is shaped by volcanic activity, glaciers, and geothermal forces found nowhere else on Earth. What I Experienced We enjoyed a night with Northern Lights while we didn't exp
A day in Oslo, Norway
Norway became my 64th country, thanks to a day-long layover in Oslo. I packed as much as possible into those hours - and discovered why Scandinavians consistently top the happiness rankings. Norway is one of the world's wealthiest countries per capita, largely thanks to its massive oil fund (worth over $1.4 trillion - that's roughly $250,000 per citizen). With just 5.4 million people spread across a territory larger than Germany, it's also one of Europe's least densely populated nations. Oslo,
A week in Jordan
Jordan was a great destination for our 4-day trip. Route: Start at Amman. Next day, full-day visit to Petra, including Petra by Night show. Then move to Wadi Rum sands and spend a night there in a cave :) Then dive at Aqaba. In the evening, watch the sunset at the \[Dead Sea]\(https://
Building Cirrina - A Web3 Finance Superapp
In early 2023, I joined Cirrina as Head of Technology to help build a Web3 superapp designed to simplify personal crypto finance management for everyday users. The Vision Cirrina set out to solve a fundamental problem: Web3 was built by geeks for geeks, making it too complicated for average users to manage assets across multiple wallets and services, understand transactions, and file taxes compliantly. Our vision was a beginner-friendly superapp that makes it
Weekend in Germany
A weekend trip to Germany to visit our relatives who had become Ukrainian refugees after the 2022 invasion. Germany, my 62nd country, took on a different meaning this time - less tourism, more family. Germany has taken in over a million Ukrainian refugees since February 2022, the largest such effort since World War II. With 84 million people, it's Europe's most populous country and its economic engine. But seeing it through the eyes of displaced family
Maldives
The Maldives became my 61st country, and what a way to end 2022. Three weeks across Christmas and New Year in what's probably the most photogenic destination on Earth. Also the first long overseas trip where I didn't bring my drone - the resorts have strict no-fly policies, so I finally just relaxed without worrying about aerial shots. The Maldives is a country of superlatives: the lowest-lying nation on Earth (average elevation 1.5 meters), spread acr
Talk at the University of Surrey
It was a great pleasure to be invited to talk at the University of Surrey, UK. It was a 1.5-hour talk with Q\&A for graduating students in crypto. Unfortunately the presentation itself wasn't recorded properly and was lost permanently :/ But what wasn't lost is the Q\&A session at the end, which is linked down below :) The topic of my presentation was: What is it like to be a crypto company? I talked through past experiences in multiple crypto companies I worked at, their successes and fail
Layover in Vienna
Another layover in Vienna - my second time visiting Austria's capital. There's something comforting about returning to a city you know. The imperial grandeur, the coffee houses, the efficient public transport - Vienna delivers exactly what you expect, every time. Vienna consistently ranks among the world's most livable cities, and walking through its streets you understand why. With 1.9 million people, it's a major European capital that somehow feels man
Stay in Riga, Latvia
Latvia became my 59th country, and Riga turned out to be a neat, compact city - even when viewed mostly through rain. The weather stayed gray throughout my visit, so I embraced it and focused on night photography instead. Turns out Riga is actually quite attractive after dark! Latvia is the middle child of the Baltic states, sandwiched between Estonia and Lithuania. With just 1.9 million people (down from 2.7 million
Stay in Tallinn, Estonia
Estonia became my 58th country, and my first impression landing in Tallinn was unexpected: this looks like Prague! The medieval old town with its red-roofed buildings, cobblestone streets, and Gothic spires gave me serious déjà vu. But Estonia has a very different story to tell. Estonia is the northernmost of the Baltic states and arguably the most digitally advanced country in the world. With just 1.3 million pe
One day at Helsinki, Finland
Finland became my 57th country, but honestly, Helsinki was more of a stopover than a destination this time. My main goal was to experience a cruise for the first time in my life - the ferry from Helsinki to Tallinn takes just 2.5 hours, but I opted for an overnight cabin to make it an adventure. Finland consistently ranks as the happiest country in the world, and Helsinki - home to about 1.5 million people in it
Stay at Kaunas, Lithuania
Lithuania became my 56th country, kicking off a trip through all four Baltic-area nations before winter set in. I chose Kaunas over the capital Vilnius - wanted to see a more everyday Lithuanian city rather than the tourist-heavy center. Lithuania is the largest and southernmost of the Baltic states, with 2.8 million people. It was the first Soviet republic to declare ind
Stay at Georgia
My second time in Georgia, and this time I spent over two weeks exploring properly. Tbilisi and Batumi - the capital and the Black Sea resort town - two very different sides of the same fascinating country. Georgia sits at the crossroads of Europe and Asia, with 3.7 million people in a territory roughly the size of West
Stay in Cambodia
Cambodia became my 55th country, and the main draw was obvious: Angkor Wat, the world's most famous temple complex. But spending a week here revealed a country with far more depth than just its ancient ruins. Cambodia is still recovering from one of the 20th century's worst tragedies - the Khmer Rouge regime killed an estimated 2 million people (about a quarter of
DeCash Send Release - Stablecoins!
As a CTO at DeCash, I'm glad to announce we have a release of our own stablecoin and the UI to manage it, send.decash.com. The technical part of it was polished really well and, compared to other stablecoins, offers: Paying fees in the transaction currency. No more "Ether" or any other currency needed except DeCash tokens to manage them. Lowest possible fees, just $0.01 per blockchain action. Quick finality
Stay at Phuket, Thailand
My second visit to Thailand, and this time I spent over two weeks exclusively in Phuket. After months of hopping between countries during my extended trip, it was nice to slow down in one place - even if that place happened to Thailand's largest island and most famous beach destination. Thailand remains one of the most popular destinations in Southeast Asia, and for good reason. With 70 million people an
Stay in Australia
Australia became my 54th country, and after three weeks there I can confirm: it's big, it's really cool, and it's really expensive. One of the top countries I've visited, and definitely one of the greatest places to live in if you can afford it. Australia is a country of extremes. The 6th largest country in the world by land area, yet with only 26 million people - most concentrated in a few coastal cities. The interior is largely empty outback. The ec
Travel to Singapore
Singapore became my 53rd country, though it was an accidental discovery. We'd planned to continue to Indonesia, but discovered during our Singapore layover that we needed a visa. Change of plans - we decided to properly explore Singapore for a couple of days, then head back to Malaysia to finish what we'd started there. Singapore is a city-state of 5.5 million people packed into just 730 square kilometers - roughly the size of a medium US city. It's g
Stay at Malaysia
Malaysia became my 52nd country, and Kuala Lumpur quickly became my favorite discovery of the entire extended trip. We ended up staying almost two months (across multiple visits), and I'm convinced this is one of the best quality-of-life-to-price cities in the world. Malaysia has 33 million people spread across the Malay Peninsula and northern Borneo. It's a multi-ethnic nation - Malay, Chinese, Indian, and
Travel to Sri Lanka
Sri Lanka became my 51st country, and I visited during one of the most dramatic moments in its recent history. The 2022 economic crisis was in full swing - the currency had lost 40% of its value, power cuts lasted 8 hours a day, and protests that would eventually topple the government were gathering momentum. Not your typical tourist timing. Sri Lanka is a teardrop-shaped is
A weekend in India
My second visit to India, and this time the mission was clear: see the Taj Mahal. I'd missed it during my 2016 visit, and it had been on my mind ever since. A quick weekend trip from Nepal was just enough to tick that box - though I was in such a hurry I only managed a single panorama of Delhi! India is overwhelming by any measure. 1.4 billion people, 22 official languages, thousands of years of history, and a pace of change that's reshaping the global economy. Every visit reveals just how lit
Travel to Nepal
Nepal became my 50th country - a nice milestone for a destination that absolutely lived up to its reputation. Three weeks here, and I can confidently say it's one of the most lovely countries I've visited. The combination of dramatic landscapes, warm people, and spiritual atmosphere is genuinely unique. Nepal is a landlocked country of 30 million people wedged between China and India, containing eight of the world's ten highest peaks including \[Everest]\(h
Teaching in Saudi Arabia's hospitals
Saudi Arabia became my 49th country, and it was a work trip rather than tourism - though I got to experience plenty of both. I came on behalf of InterSystems to conduct database technology courses for local medical groups, a unique opportunity to see a country that only recently opened to tourists. Saudi Arabia is undergoing a transformation that's hard to overstate. \[Vision 2030]\(https://en.wikipedia.org/wiki/Saudi\_Vis
War in Ukraine
This is a day when Russia decided to invade my home, Ukraine. Missile strikes all over Ukraine, in all cities, Russian troops are attacking all across Eastern Ukrainian land border. Russia not being happy with the presence of independent Ukraine is a long story. But long story short, from my point of view, last 2-3 years before the war, with our new president Zelensky were amazing years for Ukraine. At the time of invasion, just 2-3 years after Zelensky stepped in: We've got an absolutely a
Travel to Colombia
That's the second time I came to Colombia, now in a group of 8 IT specialists. Returning to a country always feels different - you're no longer a tourist discovering everything for the first time, but someone reconnecting with a place you've grown to appreciate. Fun fact: Colombia has two major cellphone carriers (Claro and Movistar). This time I purchased a different carrier from what I had a year ago. It turned out that I just wasted my money because
Travel to Panama
Panama became my 48th country during an overnight layover en route from Peru. Even just one night was enough to sense that Panama City is a unique, fast-paced place - and surprisingly expensive for Central America. Panama is best known for its canal, but it's evolved into much more - a regional hub for banking, logistics, and business. With 4.4 million people and a dollarized economy (US Dollar is the officia
Travel to Peru
Peru became my 47th country, and two weeks there confirmed what I'd always suspected: it's one of South America's absolute highlights. The Inca heritage, the Andes, the Amazon, the food - Peru packs an incredible diversity into one country. Peru has 33 million people and one of the most varied geographies on Earth. The coastal desert, the Andean highlands, and the Amazon rainforest create completely different worlds within the same borders. It's also one o
Travel to Uruguay
Uruguay became my 46th country, a quick side trip from Argentina. The weather was cloudy, but even a brief visit revealed why this small nation is considered one of the most progressive and livable countries in South America. Uruguay is South America's second-smallest country by population (3.5 million) and territory. Sandwiched between giant neighbors Brazil and Argentina, it's carved out a distinctive identity: secular, liberal, and remarkably stable.
Travel to Argentina
Argentina became my 45th country, and after a week exploring, I can confidently say it was my favorite of all the South American countries I visited on this trip. Buenos Aires alone would have been worth the journey. Argentina is a country of extremes: the 8th largest nation by territory, with 46 million people spread from subtropical north to glacial Patagonia. I
Travel to Paraguay
Paraguay became my 44th country, though I only had one day to explore - specifically in Ciudad del Este, the country's notorious shopping capital on the Brazilian border. Not exactly a typical introduction to a country, but memorable nonetheless. Paraguay is South America's most overlooked nation. A landlocked country of 7 million people, it rarely makes international news and draws few tourists. Yet it
Travel to Brazil
Brazil became my 43rd country - and the starting point for an extended South American journey. My friends and I, all working remotely in IT, decided to spend several months exploring the continent while continuing to work. Two weeks in Brazil was just the beginning. Brazil is a country of superlatives. The 5th largest nation by both territory and population (215 million people), it dominates South America geographically and economically. It contains most
Traveling to Hungary
Hungary became my 42nd country - a quick trip with my younger brother just before the holidays. Budapest had been on my list for years, and even a short visit confirmed its reputation as one of Europe's most beautiful capitals. Hungary is a landlocked nation of 10 million people in the heart of Central Europe. Once half of the powerful Austro-Hungarian Empire, it
My project DataUnlocker crosses 400 clients worldwide
My successful side project DataUnlocker now has 400 users worldwide! 🎉 This project constantly grows, getting new users without spending a penny on marketing. My strategy now is still to validate that the ad blocking community is helpless against what DataUnlocker offers, and prove that it's reliable long-term before scaling this product. Even now, we have many happy companies proxying their analytics data.
Traveling to Moldova
Moldova became my 41st country, a short drive from Ukraine where I was visiting family at the time. It's one of Europe's least-visited nations, and that obscurity is part of its charm. Moldova is Europe's poorest country by GDP per capita, a small landlocked nation of 2.6 million people squeezed between Romania and Ukraine. It was part of the Soviet Union until 1991, and the Russian influence remains visible. The breakaway region of \[Transnistria]\(https
My Carbon Footprint project at Google Cloud Next
In the past year at Google I've been working on one of the most anticipated Google Cloud products - the carbon footprint. Specifically, I've been leading its UI development. As you can imagine, this product was not only about the UI: we had a team at Google of around 40 amazing people working together to make Carbon Footprint live and announced on October 12. \_«It allows companies to measure, track and report on the gross carbon emissions associated with the electricity of your cloud usage,
Back to crypto as a CTO and a Technical Product Owner at DeCash
It all began a year ago, when a small crypto company DeCash reached out to me with questions in regards to my open-sourced solution - delegated transactions for Ethereum. Since then, I started to do consulting for this company in my free time. Now I am pleased to announce that I am leading a few powerful technical products with multiple teams at DeCash to bring them to a mass market. I truly believe that the techn
Traveling to Albania
Albania became my 40th country - a milestone that marked the beginning of a Balkans road trip. After decades of isolation under communist rule, Albania has emerged as one of Europe's most surprising destinations. Albania spent most of the Cold War as the most isolated country in Europe, under the paranoid dictatorship of Enver Hoxha. He built over 170,000 bunkers across the country, preparing for invasions th
Traveling to Bosnia & Herzegovina
Bosnia and Herzegovina became my 39th country, a brief stop on the Balkans road trip. Even a short visit reveals layers of history - Ottoman, Austro-Hungarian, Yugoslav, and the scars of the 1990s war. Bosnia is a country of 3.3 million people with one of the world's most complicated political systems - a federation within a federation, with three presidents representing three ethnic groups. The \[1992-1995 war]\(https://en.wikipedia.org/wi
Traveling to Montenegro
Montenegro became my 38th country, and I spent over a week exploring this tiny Adriatic gem. With dramatic mountains plunging into the sea, medieval walled towns, and prices still reasonable by Mediterranean standards, it's easy to see why Montenegro is on the rise. Montenegro is the smallest of the former Yugoslav republics (just 620,000 people) and one of Europe's newest nations, having declared independence from Serbia in 2006. The name means "Bla
Traveling to Croatia
Croatia became my 37th country, though I only had two days - essentially a side trip during the Montenegro exploration. Even a brief visit showed why Croatia has become one of Europe's most popular destinations. Croatia has 4 million people spread along one of the most beautiful coastlines in the Mediterranean. Since the 1990s war and EU accession in 2013, it's transformed from a recovering post-conflict nation into a major tourist destination. Game of
Traveling to Seychelles
Seychelles had been on my bucket list for years, and spending a week in this Indian Ocean paradise exceeded all expectations. The combination of pristine beaches, unique wildlife, and that distinctive granite boulder landscape makes it unlike anywhere else on Earth. Seychelles is an archipelago of 115 islands with a population of just 100,000 - one of Africa's smallest nations. It was uninhabited until the 18th century, which is why it feels so pristine. Fun fact: the Seychelles is home to the
Traveling to Georgia
Georgia quickly became one of my favorite countries. This small Caucasian nation packs an incredible density of experiences - ancient monasteries, dramatic mountain landscapes, world-class wine, and some of the most generous hospitality I've encountered anywhere. Georgia has 3.7 million people and claims to be the birthplace of wine - archaeological evidence suggests winemaking here dates back 8,000 years. The country sits at the crossroads
Traveling to Cyprus
Two weeks in Cyprus during May 2021 - a perfect Mediterranean escape! With a population of around 1.2 million, Cyprus is the third-largest island in the Mediterranean and offers a fascinating blend of Greek and Turkish cultures. Fun fact: Cyprus has the highest concentration of bars per capita in the world, and Aphrodite, the goddess of love, was said to have be
Traveling to Tanzania
Tanzania was my first African safari destination, and what an introduction to the continent. Eleven days exploring the Serengeti, Ngorongoro Crater, and Zanzibar gave me some of the most memorable wildlife encounters of my life. Tanzania has 62 million people and contains some of Africa's most iconic landscapes - \[Mount Kilimanjaro]\(https://en.wikip
My project DataUnlocker is now in public beta!
DataUnlocker is my first software-as-a-service project which turned to have a big demand and is now serving hundreds of customers worldwide! This is to record the date of its public launch.

Traveling to Mexico
A month in Mexico over the holidays was exactly what I needed in late 2020. From the Mayan ruins of the Yucatán Peninsula to the beaches of the Pacific coast, Mexico proved to be far more diverse and fascinating than I expected. Mexico has 130 million people, making it the most populous Spanish-speaking country in the world. It's home to 35 UNESCO World Heritage Sites, ancient civilizations predating the Spanish by millennia, and one of t

First visit to Vatican
My first visit to Vatican City came on a rainy autumn day, which turned out to be perfect timing. St. Peter's Square, largely empty of the usual crowds, offered beautiful reflections on the wet cobblestones - excellent conditions for photography. Vatican City is the world's smallest independent state, covering just 0.44 square kilometers with a population of around 800. It's the spiritual center of the Catholic Church and home to some of humanity's
Traveling to Portugal
Portugal stole my heart on this week-long adventure. With a population of around 10 million, this Atlantic-facing nation packs incredible diversity into a relatively small territory - from the historic streets of Lisbon to the dramatic cliffs of the Algarve coast. Fun fact: Portugal is the oldest nation-state in Europe, with borders largely unchanged since 1297! What I
Traveling to Monaco
A day trip to Monaco during my French Riviera exploration gave me a glimpse into one of the world's most exclusive enclaves. The concentration of wealth per square meter here is unlike anywhere else I've visited. Monaco is the world's second-smallest country (after Vatican City) at just 2.02 square kilometers, with a population of around 40,000. It has no income tax for residents, which explains the Ferraris and superyachts. Fun fact: Monaco's \[Monte Car
Traveling to France
A week exploring the French Riviera and Provence was a highlight of autumn 2020. The combination of Mediterranean coastline, hilltop villages, and that famous light made for excellent photography and memorable experiences.

Traveling to Italy
Over two weeks exploring Italy gave me a proper introduction to a country I'd wanted to visit for years.

Traveling to Liechtenstein
A day trip to Liechtenstein during my Swiss adventure added another microstate to the list. This tiny Alpine principality squeezed between Switzerland and Austria is easy to overlook, but has its own distinct charm. Liechtenstein has just 39,000 people making it the sixth smallest country in the world and one of only two doubly landlocked countries (the other being Uzbekistan). It's also the world's largest producer of false teeth and has more reg
Traveling to Switzerland
A winter week in Switzerland delivered exactly the Alpine experience I was looking for. Snow-capped peaks, precision trains, and landscapes that look too perfect to be real - Switzerland lives up to its postcards. Switzerland has 8.7 million people and manages to be neutral, prosperous, and stunningly beautiful simultaneously. Four official languages (German, French, Italian, Romansh) reflect its cultural diversity. Fun fact: Switzerland has enough

A winter escape to Slovakia, focusing on the stunning High Tatras! With a population of around 5.4 million, Slovakia is one of Europe's most underrated destinations - offering dramatic mountain scenery without the crowds of the Alps. Fun fact: The High Tatras are the smallest alpine mountain range in the world, yet they pack in dramatic peaks, glacial lakes, and over 600 km of hiking trails. What I Exper

Fun fact: Indonesia spans three time zones and is so vast that the distance from one end to the other is roughly the same as from London to Baghdad! What I Experience
Traveling to Qatar
A long layover in Doha gave me a chance to explore Qatar briefly. What started as a fueling stop in the desert has transformed into one of the world's most ambitious modern cities. Qatar has just 2.9 million people, though only about 300,000 are Qatari citizens - the rest are expatriate workers. It has the world's third-largest natural gas reserves, which funds everything you see. Fun fact: Qatar has the highest GDP p

Day trip to Malmo
A day trip from Copenhagen crossing the Øresund Bridge gave me my first taste of Sweden. Malmö, Sweden's third-largest city, makes for a perfect complement to Copenhagen - different country, different vibe, just 35 minutes away by train. Sweden has 10.5 million people and consistently ranks among the world's most livable countries. Malmö itself has transforme
Copenhagen and the Oresund Bridge
Four days in Copenhagen gave me a proper introduction to Danish hygge and Scandinavian design culture. This is a city that takes quality of life seriously - from the cycling infrastructure to the food scene to the perfectly preserved harbor front. Denmark has 5.9 million people and consistently ranks as one of the happiest countries in the world. Copenhagen itself is a sh
Traveling to United Arab Emirates
Three weeks in the UAE during peak summer was an exercise in extremes. The heat was intense, but so was the ambition on display - from the world's tallest building to artificial islands to indoor ski slopes in the desert. The UAE has 10 million people spread across seven emirates, though Dubai and Abu Dhabi dominate. The country didn't exist as a unified nation until 1971, and oil wealth has transformed it from a fishing and pearling econom
Database & Web Trainings for Dubai Healthcare Organizations

DreamTeam Blockchain Solution: the Token Economy Begins!
Working in a startup is something I think everyone should try at least once. Watching a business grow from a small team of 4-5 developers to a larger collective of 6 teams - and continuing to grow - is incredibly rewarding. Working closely with the CEO, having a direct impact on how things are done, and shaping the future of the brand and product. My 4 months at DreamTeam as a blockchain developer were a significant boost both for me and the company. And today, 6/21/201
Train trip to Minsk
A train trip from Kyiv, Ukraine to Minsk, Belarus. Also visited a castle nearby. Clean, nice city. First impression: all roads are so smooth!

The main reason why I decided to go this way is that this role combines everything I love and much more: blockchain, research and development, great atmosphere, great
Egypt - Sharm El-Sheikh and Cairo
Visited Sharm El-Sheikh with a 1-day trip to Cairo. The Cairo trip was tiring - we were stuck on border control for countless hours due to anti-terrorist measures. Egypt at that time felt like a "tourist processing factory": everything made for tourists. Around our 4-star hotel in Sharm El-Sheikh there was literally emptiness. All the shops on the local bazaar worked j
Tab Slider: My Biggest Browser Extension

One day in Vienna
A single day in Vienna is barely a taste of what this imperial capital offers. But even a brief visit reveals why Vienna consistently ranks among the world's most livable cities - the architecture, the coffee culture, the sense of faded grandeur mixed with contemporary vitality.
