01. About

Crafting performant,
scalable frontends

I'm a Senior Software Engineer based in Prague with 7+ years building React/TypeScript applications for enterprise SaaS, fintech, and marketplace clients across the US and Europe.

My work spans full product ownership — from architecture decisions and design systems to performance optimization and mentoring junior engineers.

When I'm not in the code, I'm usually at a climbing wall — hence lezeckecentrum.cz.
