What I'm working on

• Alhangeul for Windows & Linux — A desktop HWP/HWPX app, currently preparing for its first public release.
• rhwp for Slack — View, convert, and edit Korean documents from Slack. Available as a free beta.
• rhwp — Collaborator on the Rust/WebAssembly document engine created by Edward Kim that powers these apps.
• Hyper-Waterfall — A workflow for keeping AI-assisted development traceable, reviewable, and resumable.

I also build crop, a precise screenshot tool for Chrome, and tools to inspect and share Codex usage.
