Tom Passarelli

Building agent-native systems from the bottom up: a database, typed language, and coordination layer.

Active Projects

Fram — append-only fact-graph database built from immutable, addressable triples + Datalog.

Beagle — typed Lisp for AI coding agents; one source compiles idiomatically to multiple targets.

North — human + agent coordination on Fram; derives what's ready, blocked, and highest-leverage.

firn — typed authoring for NixOS / nix-darwin.

gjoa — Firefox fork with blocking, vertical tabs, vim navigation, and workspaces built in.
