Security engineer and Linux systems engineer based in Stockholm, Sweden.

I build Linux systems, security tooling, and reproducible infrastructure. Current work is centered on NixOS, Rust, privacy-preserving systems, digital forensics, security architecture, and systems programming.

Plausibly deniable dual-environment computing for NixOS. Uses Linux OverlayFS together with the NixOS impermanence module to run a hidden environment alongside a visible decoy. Near-instant switching, with forensic artifacts minimized.

A privacy-focused amnesic NixOS live distribution built as the reference platform for NAILS.

On-demand, isolated application environments for NixOS.

MSc in Information Security at Stockholm University

8+ years working with Linux systems. 4 years in technical roles at ETH Zürich. Work across Linux systems, security engineering, reproducible infrastructure, digital forensics, and privacy-preserving systems.

Open to selected roles in security engineering, platform, and systems work.
