Florian Hirschmann
Engineer in Munich. I build Android Automotive apps that ship in production cars - and roast espresso on the side.
01 — Projects
9+ Android Automotive apps shipping in production cars, including BMW. Built solo, end to end: Kotlin, Jetpack Compose, self-hosted backends.
I roast specialty coffee: selected origins, fairly sourced, roasted by hand in small batches in Munich.
An app store for Android Automotive OS: developer onboarding, automated quality testing, and controlled app rollouts to specific vehicle fleets and markets.
AI-first, API-first testing for Android Automotive apps. It boots your APK on Cuttlefish-powered AAOS virtual devices for smoke and regression testing before it reaches a vehicle.

03 — Beyond code
I roast espresso under my own label, Hirsch Roast — up to 300 kg of green beans a year. The rest of my free time happens in the mountains: ski touring, climbing, triathlon.
