I build developer tools, mostly in and around VS Code.
I like working on the parts of software that shape how people think and create: editors, notebooks, search, remote development, and now coding agents. The best tools, to me, inspire you to think deeply and create more freely.
- VS Code, where I work on editor UX, notebooks/Jupyter, search, remote development,
vscode.dev, and agentic coding experiences. - Jupyter, the Jupyter extension for VS Code.
- Copilot Chat, including recent work around Copilot coding agent, Copilot CLI, and Agent Sessions.
- VSCodeVim, Vim emulation for Visual Studio Code.
- PieceTree, the text buffer used in VS Code. The story behind it is in Text Buffer Reimplementation.
- sounds gucci, an experimental framework for diagnosing VS Code and chat bugs with GitHub Copilot agents and skills.
- el, a TUI for the Agent Host Protocol.
- Agmente, an open-source iOS client for coding agents via ACP or the Codex app-server.
- ACP swift sdk, a Swift client library for the Agent Client Protocol.
- Dev Tunnels Swift, a Swift client library for Dev Tunnels on iOS and macOS.
- lean, a small TypeScript CLI for Linear.
