Full-Stack Engineer

4+ years turning ambitious ideas into shipped products — B2C platforms in production, an award-winning IoT app, and engines that crunch numbers fast. Currently sharpening the craft at CTU Prague.

01 — About

Not just another
developer.

I'm Roman Princ — freelancer and Software Engineering student at CTU Prague. For the last 4+ years I've been the person companies call when an idea needs to become a product: web, mobile, backend, infrastructure — the whole pipeline.

I've led the build of a B2C commerce platform used in production, wrote a React Native app that controls IoT gateways in the field (and took 5th place nationally for it), and built an Excel engine in C++ because slow software offends me.

I dive deep into rabbit holes, learn whatever the problem demands, and ship. That's the whole pitch.
