About
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.

AI applications & automation
I design and build AI solutions that are more than a chatbot wired to an API. I connect language models to company data, databases, internal systems, and real working processes.
I build AI assistants, RAG systems, automated document processing, content tools, analytics apps, and agents capable of multi-step tasks — from architecture design through development to production deployment.
