I'm a hacker and mainly post about web security.

By profession, I am a pentester and team leader @usdAG.

I like to explain and understand things and I am convinced that the two go hand in hand.
So my posts are mostly of an educational nature.

Lately, I spend most of my free time developing CVE Crowd.
