I've been in application security for over a decade, as penetration tester, consultant, researcher, social engineering enthusiast and breaker of things in general.
Currently I'm VP Product Management at Quotium - creating rather than breaking for a change!
I also lead the Seeker Research Center, where we are constantly on the look for new techniques and exploitation vectors, as well as causing vendors to scratch their heads occasionally when we identify a new vulnerability in one of their products.
Current OWASP involvement:
