My specialization is internet security, but I got there by gaining knowledge within all facets of information technology.

I studied business informatics at the Hogeschool van Amsterdam. Nowadays I live on Curacao, but I can give great lessons via webcam. And through the possible use of team viewer or G + I can show on your computer how to configure a router, for example. Nothing is impossible ;-)
