Work

Open source, mostly. Libraries I needed and couldn’t find, plus one kernel that exists because two courses made it look easier than it was.

zstd-js

Zstandard compression in pure JavaScript — no WebAssembly, no native bindings.

Node's zlib core module reimplemented in JavaScript: Gzip, Deflate, Inflate, Brotli.

An x86_64 kernel in Rust with no blocking primitives anywhere.

An MCP server that exposes PHP Xdebug sessions, over Unix sockets or TCP.

MCP server for SSH: command execution, SFTP, and interactive shell sessions.

Change-based test selection: runs only the tests a diff can actually affect.
