I'm Marius Nilsen Kluften.

Aweb developer based in Oslo. Working for Capra, crafting sweet web apps.


I graduated OsloMet with a degree in Computer Science in 2017. I'm currently working on a master's degree at the University of Oslo in the field of Informatics.

Check out my thesis project @ nebula.no, where I've developed a FaaS prototype powered by Rust and WebAssembly!

React, NextJS, Tailwind, Vitest and React Query are among my favorite technologies to work with on the frontend at the moment. On the backend I'm in love with Rust and Elixir, while proficient in Node as well.

I have three lovely pets, two british shorthairs: Linux and Gatsby, and a Shiba Inu - Neko.

Outside of work I can either be found in the kitchen, in front of a video game, around a board game or at a table of D&D. Maybe at our cottage.
