About me

I'm a software and AI engineer with 4 years of experience, based in Brno. I build products end-to-end — from architecture and development to deployment and long-term operations. I work both solo and with teams.

I use AI-assisted development to move fast — delegating repetitive work to AI tools so I can focus on the problems that actually need thinking.

I help companies ship their products and deliver enterprise projects, and build my own on the side. I'm involved in product decisions too — not just the build side, but scoping what to build and why.

Outside of work, I spend time with my girlfriend and family, maintain a healthy lifestyle, travel, and stay curious about too many things.
