Hello there!

I built my first iPhone app Translate back in 2008. Initially it was an outlet for procrastination while I was supposed to be finishing my Ph.D. Building apps quickly grew into a real labor of love. Over the years, besides building apps, I helped various startups build, validate and grow their iOS apps.

Currently I’m a co-founder and CTO of Recast and keep building my own apps at Fifteen Jugglers.

My last jobby job was being the general manager of Keepsafe Europe, where I started the Berlin office and built a kick-ass team to build and grow apps which are used by millions of people every day.

I used to organize UIKonf together with Sabine, Bianca, Julia and Chrissy.

I live in Berlin with my wife and son. Whenever I have some free time you can find me flying gliders (real pilots need no engines!)
