Writing
I write a lot, and most of it is technical. I care about clear writing because a system nobody can explain is a system nobody can maintain.
- Academic writing. My MSc thesis (opens in a new tab) on fine-grained access control by encryption, written in Typst, plus my bachelor project (opens in a new tab). I structure them around the argument, not the chronology.
- Technical documentation. Developer docs and example bots across several tech stacks for ITU Poker Bot Battle.
- Incident postmortems. 70+ written postmortems for my own agent setup: timeline, root cause, what was ruled out, and lessons. Short and blameless.
- Blog posts. Opinionated pieces on the blog (opens in a new tab) about AI agents, self-hosting and software.
My style is short sentences, concrete claims and no filler. I would rather say one true thing than three impressive ones.

Education
Master of Science in Computer Science
Aug 2024 → presentIT University of Copenhagen (opens in a new tab)
Currently pursuing a Master of Science in Computer Science.
Bachelor in Software Development
aug 2021 → jul 2024IT University of Copenhagen (opens in a new tab)
Gained a solid software development foundation, focusing on theoretical and practical aspects as well. Completed coursework in algorithms, data structures, and software engineering principles. Worked on various projects, including a DHI project that involved developing a full-stack web application. My bachelor thesis was about hand gestures in virtual meetings, and if there exists a natural gesture set that can be mapped to actions such as volume control. Spoiler: There was not a natural gesture set. But we got a lot of other interesting findings from the data we gathered and analyzed. You can read more about the bachelor project, which was done with my partner Mads Roager (opens in a new tab).
