I work at Cloudflare, where I investigate how things break across the edge of the internet and help build the tools that solves problem.

Outside of that: I write code that escapes into the wild. Markdown editors. Diff viewers. MCP servers. Tools that solve the problem in front of me.

Based in Australia.
