About me

Experienced Full-Stack Web Developer with 7+ years.

I specialize in business process automation and scalable development — bridging code with real business value.

I've built blazing-fast frontends, engineered internal tools that saved entire teams dozens of hours per month, and contributed to game engines.

I bring structure to chaos. My work reduces friction, boosts performance, and often pays for itself in saved time or new revenue.

I'm not just a developer — I'm a system thinker, a detail-driven builder, and a problem-solver who treats every product like my own.

I love programming — but more importantly, my programming gets results.
