Summary
👤
Senior🎓
Top SchoolMads Obitsø is a research engineer based in Copenhagen with 12 years of hands-on experience across systems, backend and security-focused development. He holds a Cand.Scient. in computer science and a datamatiker background, and thrives on low-level programming (assembly, C), functional programming and toolsmithing. Mads has a strong teaching record at DIKU and elsewhere, translating deep technical topics like x86_64 assembly, fuzzing and reverse engineering into practical coursework and automated grading tools. He enjoys automating away tedious work (once replaced a job with an AWK script) and has a taste for elegant solutions while not shying from quick-and-dirty fixes to move projects forward. Notable side projects include implementing Advent of Code challenges and a Wolfenstein3D clone in x86_64 assembly without libc, and using fuzzing to uncover unexpected eBPF verifier behaviors. He seeks roles that present “impossible” problems — especially those that demand creativity at the tool and language level or constraints like restrictive C or legacy-code translations.
