Case studies
Four shipped systems, drilled to the architecture.

Agent Tutor K-12
1 concept, 5 ways · 0 curriculum stored

AI Auto Email Responder
Shipped · paying customers · never auto-sends
A live commercial SaaS that drafts your email replies over IMAP but never sends without your sign-off — from ingestion to Stripe billing, built to production solo.
SGO Compliance Ledger
Every dollar hash-chained · reconciled daily
A production donation & scholarship ledger where every dollar is hash-chained, double-entered, and reconciled against the bank daily — because 'probably right' isn't good enough for the IRS.
