About Me

I’m a passionate web developer with a focus on web application security.

Doing open source development and security reviews in my spare time is awesome for me. You find my github account in the footer of this page. If you are interested in security issues I found, see the page “Found Security Vulnerabilities”

Programming Languages

Unfortunately, I’m doing a lot of PHP. I love-hate PHP. It is one of the languages you can hardly bypass when doing web development. Same applies to Javascript.

I like programming in C# (and do it from time to time) but my real interest is in functional languages like Haskell, Closure or F#.

Learning more functional languages and doing some real project in it are on my roadmap. But right now I just have very superficial knowledge about them.
