Mach is a statically-typed, compiled, systems programming language I designed and built from the ground up. The compiler is fully self-hosted through a four stage bootstrap pipeline starting from C with zero dependencies. The project's multiple repositories include a tree-sitter grammar, VSCode and Zed extensions, and the standard library. The compiler is written specifically to not require any 3rd party tools at all, including larger language backends like LLVM.

Loom is an MCP server written in Go that gives AI coding agents a structured, opinionated workflow for GitHub. It enforces issue-driven development with convention-aligned branching, commits, and PR lifecycle management compatible with CI infrastructure. It handles repo setup, issue tracking, and the full create-branch-to-merge pipeline so that agents can participate in real codebases without improvising git commands.
