Selected work

ripwire
The ripgrep of AI context: a zero-dependency C++23 CLI and MCP server that hands coding agents a map of the repo before they read it. I wrote its native Windows port, 8,900 lines across 175 files on Clang and the MSVC ABI, built end to end with AI agents.

locoChat
Security research on the live chat of Loco, a streaming platform. Its API took the sender’s display name from the client instead of the session, so any signed-in account could post as anyone, moderators included. locoChat is the proof of concept.
