Komínek.
Products taken from an empty repository to production. A zero-trust data provenance platform, an EV charging network with live payments, and a course scheduler I still run today.
Running Kreditožrouti, live at kreditozrouti.cz
A course scheduler for VŠE students that I created and maintain alone. It scrapes InSIS, offers better search and scheduling than the university system, and runs with monitoring, alerting and automatic deployments.
Built end-to-end. Deployed. In production.
Every project below I shipped end to end: infrastructure, backend, and UI.

"Jan joined our team as a junior, just starting university. Even back then, it was clear to me that he was a talented programmer. He understands very well that as a programmer, he needs to have a broader perspective beyond just coding. He handled a great deal of work at our company, and it was always evident that he could research the context himself and ask the right questions to fill in any missing product context."
