Being a trained physicist I learned Mathematica while developing FeynCalc in 1990. Since then I am stuck with Matheamtica. I do like some other programming languages like Fortran and Java.
I work at my own company, GluonVision GmbH, in Berlin, doing mostly (web)Mathematica related consulting and projects.
Lately I became more and more insterested in CDF projects.
