About


Probably we met on some event, maybe some other reasons brought you here. Nevertheless, I welcome you.

I'm a full time TYPO3 developer since 2004. From my first "Hello World" I climbed the ladder and worked together with some of the highest skilled people in the TYPO3 community. Besides of developing TYPO3 extensions and writing tests in my daily job, I co-founded a RPG publishing company, do some mapping (as in "show me the way") and consider myself an able dancer.
