I'm crazy about the internet since the early nineties, when I set up my first uucp connection on Slackware 0.9 and a Datatronics modem.

As a serial entrepreneur, I founded and co-founded several companies including Qixxit (spin-off for Deutsche Bahn) plazes.com (acquired by Nokia in 2008), 7Moments, ally and Mission Control.

As a consultant I worked with Lufthansa, RWE, TUI, DER, METRO and others.

In my free time, I enjoy travelling with my family, making music and photography.
