I'm addiced to computers since my first computer, a C64 in 1983. I have a Bachelor (1996 FH Gummersbach) and Master (2004 University of Liverpool) degree in Computer Science. I worked as a software engineer since 1996 in several projects. Since 2004 I'm focussing on web application security, actually as a freelancer.
I'm a CISSP, CEH (Certified Ethical Hacker), ECSA (EC-Council Security Analyst) and a Sun Certified Java Programmer. Currently I'm trying to get certified as an OSCP (Offense Security Certified Professional).
