I'm Thorstein, and I've been programming both as a hobby and professionally for a decade. I primarily work with .NET and enjoy exploring the latest technologies.
In my spare time, I'm a gamer and a golfer. I've won Bedriftsligaen for CS six times with my team, and yes, I have an image of me with all the trophies. When I'm not gaming, I'm trying to improve my golf swing. Spoiler alert: my golf balls spend more time in the hazard than on the green.
I am currently working as a lead software engineer at Intility, where I build the APIs, authorization systems, and platform tooling behind software used across Intility's customer base. In addition to professional projects, I enjoy creating applications for amusement: I have built apps for tracking activity in the company gym, a game for guessing the names of my colleagues, and an advent calendar.
