I'm a programmer from Berlin and run engineering at COUP, where our mission is to transform urban mobility towards a shared, electricity powered model. Engineering stuff I like includes building passionate teams, making sense of data (RecSys, visualizations, and that kind of stuff) as well as running and understanding distributed systems. In my spare time I made an iPhone fitness app called Gym Hero and a bunch of kids. A long time ago I started the s9y project.
To save you any further googling, this is where you can reach me (save my phone number and physical address, which are left as an easy exercise for the interested reader):
