A web app for improv theatre matches: match modes, scoreboard, and a microphone-driven applause meter. Built for my own improv group.

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.
