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.
I roast specialty coffee: selected origins, fairly sourced, roasted by hand in small batches in Munich.
An interactive explainer following a single coffee bean from cherry to cup — with more than two dozen 3D demonstrations you can drag, scrub, and break.

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.
