Hi, I'm Jan 👋
Tech founder and hardcore engineer from the Czech Republic. I deployed my first web application over 20 years ago and never really stopped.
Serial founder, software architect, PHP geek by origin. I build products end to end — from the database migration to the pricing page — and I take on the problems other people have already given up on.
I was trained at Salesforce and Oracle in San Francisco and at Google in Palo Alto. Still one of the things I'm proudest of.
Whatever can be built in the open, I build in the open.
● currently: busy, caffeinated, shipping
what I do
- Building awesome productsStartup spirit through and through, and stubbornly challenge-driven. I start products, run them, and stay close enough to the code to still be useful at 2am.
- Engineering & architectureI genuinely love technical debt. Taming legacy code at scale is a rare skill, and it’s the one I’m best at — alongside system architecture, CI/CD, containers and performance.
- SharingI love open source. Whatever can be public, I make public — and I speak at meetups and conferences about what I learn along the way.

MySpeedPuzzling.com
The largest speed puzzling community database in the world, built from scratch and bootstrapped. It is a nights-and-weekends hobby that quietly grew past 11,000 users — and it is fully open source.

…and many more. Consulting and advisory alongside it.
things I love talking about
I used to be a sceptic about AI. Then I actually used Claude Code properly, and now I run twenty things at once and feel a bit like a superhero — which is exactly as exhausting as it sounds. 🙂
