About me: I'm an OMVP currently working as a senior developer at Neoleaf AB in Stockholm. Originally I come from the northern part of Sweden, but I moved down here after I got my degree from Luleå University of Technology in early 2008. If I am not behind the keyboard coding, I am probably lifting something heavy, making holes in paper from a distance, or working on a bestseller. Photo by Viveka Österman
