pqp
A quantum-resistant GPG emulation in Rust, key management, encryption and signing using ML-KEM and ML-DSA instead of RSA.

Computing
Where I work closest to the machine. Open-source projects, experiments in systems and cryptography, and occasional essays about the craft.
Open source
Selected projects
Small, focused tools I build for myself and share on GitHub. Most are conservative in scope and obsessive about correctness.
pass-pqp
A drop-in replacement for pass, your password
store, git-backed and post-quantum. Every secret encrypted with
the pqp stack; pure POSIX shell, no GPG agent.

pass-pqp-ff-extension
Brings the pass-pqp store to Firefox and LibreWolf. A popup matches the current domain, searches the store, and copies usernames and passwords via a native messaging host.

fem
CLI email management in Rust. Pulls IMAP into a local Maildir, pushes over SMTP, and searches, tags and transforms messages with hooks. No daemon, no GUI.

tl
A social network built on top of git. Every post is a commit, every friend a submodule, every identity a SHA3-256 hash. Your timeline is a repository. Fork the world.

Notes & essays
Thoughts about computing
Longer reflections on building software. Full posts appear in the Journal.
How models changed the way I code
The bottleneck is no longer writing code. On writing skills, knowing the model you are teaching, and designing the whole application before a single line exists.
A social network built on git
Every post is a commit, every friend a submodule. On a timeline for hackers, where identity is a hash, follows are consent, and the network resists censorship by construction.
Emails are just files
No daemon, no GUI. On managing mail as a directory of messages with a CLI utility, and the handlers and hooks that make it as capable as any client.
Why we need a post-quantum replacement for GPG
RSA had a good century. The privacy case for moving from RSA to lattice-based cryptography, the options that already exist, and what trusting Rust libraries means.
The quiet case for plain text
Markdown, symlinks and grep: an argument for software that keeps your data readable a decade from now.
Small tools, long lives
Building unix-philosophy utilities in 2026, what still holds, and what the modern stack gets wrong.
