Before I became a pensioneer, I was employed in a heavy metal company. For a while I had to develop applications for the development and controlling departments. Mainly I coded with dBase and Turbo Pascal. Later I programmed PLCs.

In 2019 I started coding with Java in order to create virtual synthesizer modules. That project is named Polymond, where my 'P' avatar is coming from.

For another private project I'm programming an Arduino controller with C++. Therefore I used Arduino standard libraries as well a libraries, wich were created by other people and stored on GitHub. Because I also had to create own libraries too, I found it a good idea to publish them here.
