Projects

CleverCrow

2026

Built a way for open source maintainers to get paid to work their backlog. Users back the GitHub issues they care about, and when a merged PR closes one, the pool pays out to the maintainer. No workflow changes, no bounty-hunting PR races, just little by little.

Erg

Built a workflow orchestrator for Claude Code. It watches your issue tracker, spins up containerized AI sessions to implement the work, creates PRs, handles review feedback, monitors CI, and auto-merges. Written in Go, available via Homebrew.

Plural

2026 · Archived

Built a CLI for running parallel Claude sessions. Because sometimes you want to try three different approaches without losing your place. Written in Go, available via Homebrew.

Rush Programming Language

2025 · Archived

Built an experimental programming language from scratch using AI pair programming. Functional + OO paradigms, three-tiered execution (interpreter → bytecode VM → ARM64 JIT), and surprisingly fun to write.

Intro to Transformers

2025

Wrote a book that teaches transformer architecture from first principles. Covers building transformers, understanding gradients, and generating images from noise.

Singular

2017

Wrote a science fiction novel called Singular. Vintage computers, artificial intelligence gone rogue, the fate of humanity.

Los Alamos National Lab

Intern

Wrote modeling software for the Sudbury Neutrino Observatory. I had a virtually insignificant role, but the project’s chief scientist won the 2015 Nobel Prize in Physics so it’s still cool!
