About

I'm a Full-Stack Engineer with 5+ years building scalable web applications, SaaS platforms, and OTT products. I've shipped Smart TV apps to millions of users on Samsung, LG, Philips, and Hisense; built a blockchain talent marketplace that reached 500+ users; and helped improve load performance by 20% and revenue contribution by 15% at a European sports media company. I work primarily in React, TypeScript, and Next.js, with a strong Node.js backend layer. I also integrate AI tooling (Cursor, Claude, Codex) into my daily workflow not as a trend, but as a genuine productivity multiplier.
