I am a computer scientist and a Mathematica and WolframAlpha enthusiast. I am working on the field of Cryptography, High Performance Computing, Algorithm Design.
My other interests are Image and Signal Processing (mainly because the topics above are rather dry so I am sometimes really happy to see an image or a plot appear ;) )
I am using Mathematica mainly to develop new algorithms and/or specific data structures.
Since 2 years I'm working as a freelancer in the cryptography/signal-processing field. Before that I was a regular employee for different companies.
