Paul Julian Heise

Senior Software Developer

/ Bio

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

Shipping software since 2014. Two of my own companies along the way. Today I build and renew web applications for companies: modernizations, MVPs and app checks, each at a fixed price. The instinct never changes: build it, ship it, make it better.

I run my own business as an independent contractor (OSVČ) in Prague, with my own offers and my own tools. Ambitious. Restless. I love making things. AI makes me fast, experience keeps it right. No excuses.

Path

The path since 2014. Building, leading, shipping.
