I am a freelancer for 3D Graphics (mostly Blender since 1998), teacher (BFCT) and author of Blender documentation. 

My main strength is to teach Blender and provide companies with 3D graphics and animations, mostly with technical, engineering or medical contents due to the fact that I have a diploma in "environmental biotechnology". Due to my work in the last 10 years using the Blender Game Engine (BGE) I also do many interactive stuff (not only games) with Blender.

I teach and write in my native language German as well as in English. I am located in Berlin, capitol of Germany but willing to travel.
