About

I started my journey in Novosibirsk, Russia, studying software development — and never looked back. Over the past decade, I've been building complex mobile products from the ground up.

From native iOS apps to cross-platform React Native solutions, from Web2 to Web3 — I thrive in turning ambitious ideas into polished, production-grade products that millions of people rely on daily. As a Tech Lead, I bridge the gap between engineering excellence and real business impact.
