01Projects

Atrium

A social space like Discord, with collaborative apps built in.

A home for spaces, both social and private. Social spaces work like a Discord server: open communities anyone can find, join, and read without an account. Private spaces work like Slack: a workspace for a team, a club, or a group of friends, where everything stays with the people invited. Every space has channels to talk in, documents people write together, and an inbox that tells you what changed without copying the messages into it. It runs on Yttrium.

Atrium/ˈā-trē-əm/noun

The open central hall of a building, often lit from above. In a Roman house, the main room, open to the sky, that every other room opened onto.

Zij

Cloud spreadsheets rebuilt for agentic workflows. Call LLMs, query databases, or hit APIs on every row, in a spreadsheet you already know.

P-03live

Yttrium

A TypeScript sync engine built to scale on Cloudflare Workers and Durable Objects. Caching, permissions, cursors, and other batteries included, tested from A to Z: Atrium and Zij.

P-04live

Rubedo

A Python library that caches each step of a workflow to disk, so iterating never repeats work and batch runs are easy to see.

Collagist

Collaborative collages and collage animations. Think tldraw, but made for dense collages.

02About

I spent three years at Google Nest doing networking and WebRTC for Google Home devices to make actual phone calls, then built full stack LLM tools for program managers at ARPA-H, the new US federal health agency. Now I’m a technical founder at the Atrium Town Company, building multiplayer agents in Atrium, the all-in-one collaborative workspace.
