I build Sportera, the platform mapping free public sports venues across the Czech Republic. The map has 1,147 of them in 383 towns. I decide what we build and where it goes next, and I run the partnerships and city deals that pay for it. I came up through the code, so the technical calls are mine too.
“We love basketball and football, but we had nowhere to play and no one to play with. Most team sports can’t be played with three.”
Lead the roadmap and decide what gets built next. 1,147 venues across 383 towns, live and growing.
Negotiated our three-year Decathlon deal. In 2026 Česká spořitelna joined. Co-led campaigns that reached 800,000+ people.
Municipal deals from first meeting to paid order. Brno’s data office issued the first one, and the city lists Sportera on its open data portal.
Own the architecture, the stack and production releases. React, Firebase and Postgres. From database design to monitoring.
Growing Sportera’s work with cities. Our partnership with Česká spořitelna is signed and their campaign runs on the map. Next up is a reservation system for .

— For six months our map thought Bad Schandau was Žandov. True, just a different Žandov. I pull town names from an API with a Czech parameter, and in Czech Bad Schandau is Žandov. But Žandov is also a town in the Česká Lípa district, so a venue from Germany landed in our Czech stats. Nobody noticed. The fix was one line.
— The state has photographed the whole country at 12.5 cm per pixel. Free, no API key, CC BY 4.0. I deployed it as our map’s satellite layer. Now I also use it as the fallback image for venues without a photo. It was made so rapeseed subsidies couldn’t be faked. Updated every two years.
