Hi, I’m Harro!
I’m Harro, a software engineer and computer science student in Hamburg. I build apps, backend systems, and AI products from the first sketch to release. 💻
I currently work on IoT and IT architecture at Deloitte. Before that, I built internal software at ECE and worked on web and mobile projects as a freelancer.
I built ElevenStoic as the sole developer: design, onboarding, paywall, backend, and analytics. With CuePath, we won the Disability Tech Hackathon. 🏆
I’m part of AI Beavers and House of AI, and I contribute to Open Source @ TUM. Building together, sharing knowledge, and staying in touch after the hackathon. 🤝
🎓 Computer science at the University of Hamburg
📱 Launched 5 mobile apps
☕ Coffee, tennis, and skateboarding
🏙️ Hamburg day to day, Munich on the moodboard
On my laptop: Swift, TypeScript, Python, Claude Code, and usually too many open tabs. ✨

Harro joined the Microsoft for Startups program with a clear focus on building his own products. He brings the technical skills to turn an idea into a working app and the independence to keep moving it forward. It was a pleasure to support him as a founder.
