Small systems software, local-first developer utilities, and wire-level tools.

I write low-overhead software in Rust, Go, and TypeScript. Most of my work sits between Unix sockets, SQLite write-ahead logs, and deterministic CLI workflows. I ship the pieces that stay useful and archive the prototypes that do not earn their keep.
