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 live on the Play Store and shipping in production cars, including BMW. Built solo, end to end: Kotlin, Jetpack Compose, self-hosted backends.
A web app for improv theatre matches: match modes, scoreboard, and a microphone-driven applause meter. Built for my own improv group.
Recipe swipe cards for a nutrition counseling practice. Deliberately small: vanilla JS, no build step, no framework.
Earlier: iOS app and Bluetooth stack for OSRAM Smart Textiles, mobile work for Adidas, and a single sign-on app used daily at Audi (2013–2022).

03 — Beyond code
I roast espresso under my own label, Hirsch Roast — about 280 kg of green beans a year. I do improv theatre with Improveritas in Munich. The rest of my free time happens in the mountains: ski touring, climbing, triathlon.
