Developing the Fortuna mobile betting application — one of the largest sports betting platforms in Central Europe. Focused on the odds/offer section, collaborating with backend teams on data loading optimization and performance.
Developed e-commerce features for the ROSSMANN CLUB app (1M+ downloads). Implemented delivery via Zásilkovna, product video previews, search improvements, and a blog section.
Led the complete rewrite of Moje Studium from Xamarin to native Android, including UI/UX design. Significantly improved user ratings. Also worked on university information systems.
Took a detour from tech to work in the Scottish Highlands. House porter at a luxury hotel, then team leader at a restaurant. Learned leadership, communication, and that coding beats carrying luggage.
The largest independent driving school comparator in the Czech Republic. A Turborepo monorepo with 3 Next.js apps, a Hono/tRPC backend, 80-table PostgreSQL database with PostGIS, an AI-powered price extraction pipeline monitoring 1,700 school websites, and a fleet of 20 parallel Claude Code agents (the "Ralph method") that autonomously validated every school in the country. Solo-built with AI as my co-pilot.
