I'm a programmer from Berlin working in backend engineering at COUP, where our mission is to transform urban mobility towards a shared, electricity powered model. 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):
