I build distributed systems and the tooling around them — from IBM's mainframe-backed support portal, to satellite ground stations in Go, to the AI agents that now keep Indeed's systems reliable.
appletalk
An AppleTalk protocol stack: an EtherTalk sniffer, a node that joins the network and queries it, a bridge for emulated Macs, and an AURP router.
clarus
A small, compiled, event-driven language for native System 6/7 apps on 68k Macs. Self-hosting, and the compiler also runs on the Mac.
virtualtreasury-tools
Offline archive, full-text index, LLM name extraction, and a terminal browser for the Virtual Record Treasury of Ireland.
