Open source
Fixes and features merged upstream in the Ruby & AI libraries I build on.
Most of my open-source work goes into the projects my own Rails and AI code depends on — RubyLLM and ActiveAgent today, React on Rails and Rails-ecosystem gems before that. The common thread is reliability: cancellation and concurrent tools, provider protocols, attachments, structured output, tracing, evals and cost accounting, and making it all behave inside a Rails app.
