Security researcher and developer, Oslo

I break systems, then build the tools that catch the next break.

now finishing a BSc in Cybersecurity, building Riposte and Futtia.no

about

I am a cybersecurity student in my final year of a BSc at Høyskolen Kristiania, Bergen campus. I work at the intersection of offensive security and software development: I like understanding exactly how a system fails, and then writing the code that makes the next failure visible.

I compete in CTFs, mostly crypto, pwn, and web, and I volunteer as a developer at Kvarteret studenthus. My current focus is whether AI coding tools actually produce secure code, the subject of my bachelor thesis and the idea behind Riposte, an offline purple-team platform I build with Krister Eriksen.

projects

Riposte
[ in dev ]

An offline AI purple-team platform. Red and blue agents run a four-gate verified-detection loop, so every simulated attack is proven caught or missed. Fully offline, hundreds of tests.

github
Futtia
[ in dev ]

AI football analysis. A TypeScript / Bun monorepo that turns match footage into queryable, watchable insight.

Bachelor thesis
[ 2026 ]

Secure AI-Accelerated Development in Agile Workflows: A Framework for Small Teams. How small teams can fold AI-accelerated development into an agile workflow while balancing security, architecture, and reliability without losing innovation or parallel collaboration. The answer is SAIF, a five-part framework, grounded in a security experiment across four AI coding models and a semester building inside the ToSee AS startup. A group thesis with Bendik Hagen and Krister Eriksen.
