I got an M.Sc. in computer science from the University of Helsinki in 1995. Until 2015, I worked as an application software developer in Helsinki, Vancouver, and Auckland. I coded mostly in Java, C++ and Rails, on a number of platforms, including Linux/UNIX, Symbian, and Windows. In the 2010s, I also studied and worked on full-stack web development, mostly with Ruby on Rails.
In 2015, I changed my career path slightly by going into Linux systems administration for a health technology startup in Helsinki.
