I build web applications end to end: the interface, the API behind it, and the data underneath.

About

Writing software since
2021
Working at
Trii Software
Based in
Oslo, Norway

I came to software in 2021 for the place where design meets engineering: interfaces that look considered and hold up in real use.

Since then I have finished my studies, along with courses and certifications, and at Trii Software I work on web applications with an eye on performance, scalability and code quality. I like a hard problem, and I am always learning new technologies and better ways of working.

Away from the screen you will find me with a good book, somewhere outdoors, or under a barbell.
