Started with Delphi when I was about 10 and it was still property of Borland.
Mostly worked with Java
My still biggest project is a 3D OpenGL Maze Game that was programmed in Delphi. You can read more about it here (german)
I know I need to get my hands dirty with OpenGL again soon.
Currently I'm studying Computer Science at the University in Bonn. Here I like working low level with C and Go on network code. I also enjoy hardware design and math.
MOST INTERESTING FACT ABOUT ME:
I invented Google Plus. Well somehow. I was working on a social network similar to facebook with the difference that you have huge control about who can see what. You could put people in Groups (Circles) and specify what post or profile infomration you want to share with which group. After I heard about Google Plus I stopped development.
