/ Bio

I'm Paul. Senior software developer, originally from Germany, now working remotely from Prague.

Ten years of shipping software. Web apps, APIs, databases. Two of my own companies along the way. The instinct never changes: build it, ship it, make it better.

Ambitious. Restless. I love making things. I work with AI on every step. I move fast and ship clean. No excuses.

(01) / Path

A decade of work. Building, leading, shipping.
