My name is Zef Hemel. I’m Dutch, yet I live in Poznan, Poland.

I went to school for a while (B.Sc. in Computer Science from the University of Groningen, M.Sc. from Trinity College DublinPh.D from Delft University of Technology), then I worked for Cloud9 IDE and architected their language analysis infrastructure, and later became VP of Engineering.
