I am a 29 years old guy and I live with my girlfriend in Hoegaarden, little city from Belgium well known for its white beer
.
I studied as an industrial engineer in electronics but I oriented myself more towards software development when I started to work.
Currently I am working in a research centre in mechatronica. I mainly develop in C++ but I also do a bit of Java.
When I have so spare time, I like to read (mainly fantasy) and play electric guitar.
