I build small, carefully documented tools – mostly in Rust and C++ – around security, embedded devices and home infrastructure. I prefer written specifications, signed commits and honest limitations over big promises.
Current focus: PQKeep, a command-line tool for post-quantum key generation and storage (ML-KEM, ML-DSA, AES-256-GCM, Argon2id) – in early development and not yet audited.
- Every change starts with a short plan and ends with CI, tests and a signed commit.
- I develop together with an AI coding assistant (Claude by Anthropic) and say so in each project; design decisions, review and releases stay with me.
- Security issues: please use the private reporting link in the respective repository.
