This domain mainly hosts my email address and a few services I personally use. I'm afraid there is not much in the way of public-facing websites here, at least not yet.
I am a software developer living in Cologne, Germany. I work mainly in server-side development of Java and PHP web applications. My specialty is the development of RESTful APIs, with the hope that developers working with them will find them pleasant to use.
I am also a volunteer at the German Federal Agency for Technical Relief (THW), the German government's disaster relief agency. It is almost entirely staffed by about 80,000 volunteers.
If you'd like to contact me, feel free to send me an email at email@example.com. You can also find me on Twitter, Facebook, Github, LinkedIn and Xing.
