Welcome to my GitHub profile — I'm Dion, a full-stack software engineer based in NYC – originally from 🇩🇪 – with over a decade of experience building scalable, performant, and high-quality web and mobile applications.
- 🎓 Started programming at 13 and developed my first iOS app by 14
- 🚀 Co-founded my first startup (fintech) at 23, including developing a large B2C financial platform and other financial products (difyol.io, RoboRente)
- 🧠 Studied Applied Computer Science at Universität Duisburg-Essen (80% completed)
- 💻 Self-employed since 2017, mostly freelancing for agencies and building web & mobile apps for major brands
- 🌍 Lead developer for a global B2B customer portal from 2018 to 2026
- 🗣️ Joined BoldVoice as a full-stack engineer in 2026
- 💻 Built small & native utility apps with more than 200k downloads (with TinyStopwatch being in the top 25 of utility apps several times)
- 📸 FolioHire – a marketplace for photographers and the people who want to work with them. The platform handles discovery, scheduling, and briefs — so both sides can focus on the shoot
✈️ FlyCo (retired) was a non-profit flight emissions compensation app
