Being a trained physicist I learned Mathematica while developing FeynCalc in 1990. Since then I use Mathematica extensively. I do like some other programming languages like Fortran and Java.

I work at my own company, GluonVision GmbH, in Berlin, Germany, doing mostly (cloud)Mathematica related consulting and projects.

Lately I became more and more insterested in Enterprise CDF and cloud projects.
