I build tools for Linux and software development, from keyboard hardware support to desktop applications and testing libraries. My interests include systems programming, Linux internals, and experimental tooling.
Lost the tail, kept the curiosity.
| Project | What I built | Explore |
|---|---|---|
| Dareu EK75 + OpenRGB | Keyboard lighting support over USB and a wireless receiver, with protocol research and tests that run without the hardware. | Protocol notes |
| Feader RSS | An RSS reader for Omarchy with a Go backend, SQLite storage, full-text search, and backup/restore. | Screenshots and installation |
| Cest | A header-only testing framework for C and related languages, also used by the Dareu controller tests. | Quick start |
- iae: editor, coding agent, shell, and git in a tmux workspace that adapts to terminal size.
- Sword Art Omarchy: an Omarchy theme inspired by Aincrad, with screenshots and installation instructions.
- Dotfiles: my Linux and Windows setup, tested installers, and a library of coding-agent skills.
