First OSS Contact

My first computer was an Amiga and it was on this machine that I learned to write software using Assembly and C. In the Amiga free-software community I had my first contact with Open Source, for instance I remember using PasTeX (the University of Passau's LaTeX distribution).
Unfortunately, the Amiga's operating system was not Open Source so its excellence was lost due to its proprietary and closed nature when Commodore went under.

Contributer in OSS-Projekt

I have created, and still maintain, PHPUnit. This testing framework is regarded by many as industry-leading testing and having played a vital role in professionalizing software development with PHP. I also maintain around 50 other, PHP-related Open Source projects on GitHub that are either dependencies of PHPUnit or related to it as well as other tools such as PHPCPD or PHPLOC. I also contribute to PHP itself when and where I can.
