I'm a software-developer and entrepreneur.
Currently I'm working as a senior rails developer for Wimdu.com
An interesting startup I founded in 2008 is Spekunauten.de, a stock market simulation and live trading plattform (German).
I worked a lot with Ruby (+Rails) recently. At the moment I'm trying to read Seven Languages In Seven Weeks to widen my horizont.
