// Software Engineer

Bjørnar Hagen.

I build, break and occasionally fix software — full-stack, infrastructure, and the chaos in between. Currently building software at Gokstad Akademiet.

01
Personal

Born and raised in Larvik, Norway. Currently living in Sandefjord.

I’ve always loved building and taking things apart, so when I at a young age was introduced to computers, it didn’t take very long before I was taking them apart and learning about how they worked. When I was 14 I saved up scholarship money originally meant for school equipment to instead buy computer parts so I could build my first desktop computer. Once I had that built, I started learning about code and software. I was instantly fascinated with the web technologies and building websites. Since then I’ve learnt more and more about programming and different software technologies.

Career

I learnt HTML, CSS, JS and PHP through self study and got a few gigs through some close friends. Later on I got my first “real job” as an apprentice at Optimale Systemer in Larvik. Around the same time I started the company Datahjelpen so to take on extra jobs outside of work and school.

After 2 years at Optimale Systemer I had learned a lot and considered myself a full-stack web developer, though still very much a junior. I now knew how to setup the LEMP stack from scratch on a VPS, and I could make both the front-end and back-end of a webapp. After this I moved to Halden to start on my Bachelor of Science in Computer Engineering at Østfold College University.

3 years later I got my degree and moved to Sandefjord, where I still live. I started working full-time in Datahjelpen. After a good year, Covid unfortunately became a thing. I had to find a more stable job as no one was willing to start new projects at the time. That is how I ended up at Adstate, where I stayed for 4 years.

After Adstate I spent a year at River Security as a senior full-stack developer, building tooling for continuous offensive security — attack-surface management and always-on penetration testing.

In 2023 I started NUVA with a couple of friends.

I’m currently working full-time at Gokstad Akademiet.
