Alistair Smith

I work at Anthropic on Bun and Claude Code.

Before that, I built a cloud platform and an AI research app on early language models. I've worked on software with 100M+ monthly downloads and lots of open source. I'm interested in interpreters, language design, and excellent products. It's nice to meet you.

Currently in San Francisco, CA.
