Senior🎓
Top SchoolJan Rychnovsky is a senior Android developer with nine years of professional experience and a decade-long freelance background building high-traffic and niche mobile apps across Czechia and Central Europe. He helped develop IDOS, the Czech Republic’s leading public transport app, and has led Android work for smart-city and payment terminal projects, demonstrating strength in constrained, embedded Android environments. Currently at TangibleCodes he contributes to the Zcash mobile SDK and is building a first-party Zashi wallet, combining security, privacy, and practical SDK design. As founder of Daylee he applies UX and motion design sensibilities to a video-diary app that showcases advanced media processing (FFmpeg) and serverless integrations. Colleagues describe him as detail-oriented, improvement-driven, and comfortable owning projects end-to-end, and outside work he recharges by backcountry skiing, mountain hiking, and family campervan trips.
