st0012/README.md

I'm a Ruby committer from Taiwan, working on Shopify's Ruby Developer Experience team.

I maintain IRB, RDoc, and Reline — tools that Ruby developers use daily. I also contribute to Rubydex (coming soon), Ruby LSP, and ZJIT.

Right now I'm focused on improving Ruby's documentation tooling — better markdown support, RBS signatures, and making docs work well for both humans and AI agents.

I write about these at st0012.dev.
