Projects

Developer environments, low-level experiments, and shipped products — the work I keep coming back to.

context_forge

A Claude Code plugin that keeps the agent's context small: a status line with a live context bar and CLAUDE.md token estimate, a session-start hook that warns when an instruction file grows past 600 words, and 11 skills for trimming it further — six of them also run on Codex and Gemini CLI.

NyanVim

A small, fast Neovim setup: IDE features out of the box, ~30 ms startup, a live theme switcher, and a try-before-you-switch installer that leaves your own config untouched. About 1,200 lines of Lua, one plugin per file.

Shipped products

NyanPhotos

A macOS app that sorts your Apple Photos library by what the pictures are: screenshots, documents, anime art, tiny or low-resolution files, duplicates and bursts. Every label comes from on-device Vision and image embeddings, nothing leaves the Mac, and every change goes through a review sheet before Photos is touched.
