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, count revenue or conversions of their marketing

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 trip was to see the National Library of Kosovo, famous for its striking and unconven

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

Romania, the country of Dracula, famous Transfăgărășan (the "most beautiful road in the world"), outstanding mountains and nice nature overall. This car trip was full of surprises, and my goal to see the bear was still left intact :)

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

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.

A few days spent in Morocco. Wonderful and warm country! It was just $100 round-trip from Katowice, Poland during the Winter. Turns out, Morocco is great for surfing. Next time surfing is going to be included! Guess what was the main thing to see here? Goats on trees! 🤩

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

A quick weekend in Germany visiting our relatives - Ukrainian refugees.

Maldives is a very popular honeymoon destination, along with the one having the most expensive over-water hotels in the world. This is also the first long overseas destination where I didn't take my drone :)

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 in, their success and failur

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, comparing 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 finalit

Sri Lanka is lovely. However, we made it to Sri Lanka just when local protests were on fire. No lighting for 8 hours a day, 40% of Sri Lankan currency just lost and so on... Though, it didn't make much difference as for the tourist, except things being even more cheaper around.

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 in 2-3 years after Zalensky stepped in: We've got an a

Two weeks in Peru - such a fantastic journey!

A week in Argentina! In South America, it was the country I liked the most.

My friends and I, who are working in IT industry and can afford traveling the world while working remotely, decided to start our work-from-South-America journey. We will try to visit as many countries as possible, given COVID-related restrictions.

My successful side project DataUnlocker now has 400 users worldwide! 🎉 This project constantly grows, getting new users without any penny spent on marketing. My strategy now is still to validate that ad blocking community is helpless fighting with 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.

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,

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 th

Google always was a special and somehow awaited company for me, and today I am happy to be joining it at the very beginning of 2020 as a Software Engineer. New decade, new adventures! I always wanted to realize how such big companies work from the inside out, and now in my 24, I can tell that this is the last wanted piece added from my knowledge.

The date of my graduation! It has been quite a long time since I started my university, create more than 100 pet projects, got my first job and did a couple of significant side projects. 6 years of education is behind. 5 years of professional part-time experience with over 8 years in IT in total are behind as well. Today is the day to reach new heights and continue to think wide open, as always. I did my best to get my master's diploma with honors. Now, it's time to bring significant thin

But I also won a little prize — a bottle of champagne and a branded T-Shirt! Thanks \[Yggdras

It was fun and a tremendous experience both for me and the students.
