Products I've Built

Every web app hands its code to every visitor. Your paywall check, your pricing rules, the license check in your desktop app, the anti-cheat in your game — all of it ships to the user's device. And in 2026, anyone can paste that bundle into an AI agent and get clean, editable source back in minutes, together with a one-line patch that unlocks your paywall. Yesterday I launched AfterPack — my…

For months, the AfterPack waitlist — a launch page I put up for my upcoming product — did one extra thing after you entered your email: it popped up a small box asking what matters most to you. <img src="https://r2.nikitaeverywhere.com/2026/06-04-waitlist-welcome-old.png" alt="The AfterPack post-signup screen — after you enter your email, a single free-form box asks what matters most to you.…

I hate spam. But even more, I hate emails that look legitimate yet add zero value — the kind you glance at, realize it's just another "We updated our Terms of Service" notification, and delete. I'm registered on 1000+ websites accumulated over 15+ years. Even if each sends one Terms & Conditions update per year, that's roughly 3 emails per day. Every single day. Three more distractions pulling me…

Fifteen years ago, at the beginning of my software engineering journey, I wish I had a mentor. Someone senior — a CTO, a founder, anyone who'd been through it — to sit down with me for half an hour and explain how it all actually works. Not the syntax. The thinking. Patterns. Reality. I learned by Googling. The skill back then was asking the right query, finding the right article someone wrote…

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. <Callout type="tip"> Important to know: Google Calendar has a dedicated "Out of Office" event type — selectable in the event type tabs — that auto-declines meetings and…

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…

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…

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. How Many People Lost Their Google Maps Timeline? Google never published a…

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…

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…

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…

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 weeks)…

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…

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…

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…

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…

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.…

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…

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…
