Welcome

to the web home of Johannes Willkomm. I am a freelance software developer, programmer and IT consultant based in Aachen, Germany.

I provide consultancy and software development with a dual focus on both web services and numerical computing, especially MATLAB. I am an expert in web technologies such as HTML, JS, XML and XSLT and also proficient in many numerical and technical computing languages, primarily Matlab, but also C++, C, and Fortran.

Tutorials and workshops on automatic differentiation, and especially for the software ADiMat (Automatic Differentiation for Matlab), which I have helped to develop, are also on offer.

For the R language I have created the automatic differentiation tool R/ADR.

I am currently looking for new projects to participate in. Feel free to contact me.
