About Stefan Helander
I was born a nerd! As a child I was fond of fiddling with all kind of thechnical stuff, discovering how things work and often fixing them. As a 6 year old I fixed my grandmothers 220 volts wiring.
The interest in technical stuff grown even bigger in the teenage years where I got my amateur radio license and developed a keen interest in computers.
Today I am proud to be a nerd. It is a part of my profession.
To all of you nerds and geeks out there - remember that nerd is the new sexy! :)
