Android Developer · Systems Builder · Founder
Systems builder with 5+ years of experience across Android, web, and AI. Currently a Group Developer at Fortuna Entertainment Group, building the core mobile betting app for Central Europe. In parallel, I am co-founding Tuela — a family safety app — and founded Kvalty.cz, the largest independent driving school comparator in the Czech Republic. Most of my work sits across mobile engineering, product thinking, and AI — I like being in the middle of all three.
Co-building a family safety app that helps parents know when it is time to talk to their child while keeping everyday messages private. I define the product and its vision, lead the brand and technical direction, and own security and privacy across the mobile apps, backend, and serious online-risk detection system.
Built and operate the largest independent driving school comparator in the Czech Republic. Turborepo monorepo with 3 Next.js apps, Hono/tRPC backend, 80-table PostgreSQL + PostGIS database, AI price extraction pipeline, and the "Ralph method" — 20 parallel Claude Code agents that autonomously validated 1,700 schools.
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.
