I am math and computer science teacher at a German highschool.
During my university studies I get to know LaTeX and became a big fan of this great piece of software. In the meantime I produce almost all of my documents with LaTeX. Because I also use it in my daily work at school for typesetting exercise sheets, exams etc., I decided to create my own documentclass. It is still under construction (and will definitely be for a long time) and a hard piece of work, but it makes a lot of fun and is great to learn many aspects of LaTeX.
Furthermore, I like programming in general, am supporter of open source software and a big fan of Linux (using Linux Mint at the moment). And if there is still some free time, I love playing video games, drums or ride rollercoasters. :o)
