I was born in 1982 near Stuttgart / Germany and began my first steps in programming computers at the age of only nine years on an old Commodore CBM 7072. In 2002 I finished my education as IT specialist for software engineering and did my civillian service afterwards. Currently I'm working as leader of the software division in a bigger company located in south west Germany, mainly on software development and research projects for multimedia terminals and user recognition/verification systems.
