What I've Built

Durable Agent Engine — Fault-tolerant LLM agent orchestration on raw Postgres. SELECT ... FOR UPDATE SKIP LOCKED durable queue, idempotent DAG execution, crash recovery via lock-TTL reaper, cross-process pub/sub on LISTEN/NOTIFY. No Redis, no managed queue. Proven with a chaos test that SIGKILLs workers mid-run. Node.js PostgreSQL WebSocket Docker — GitHub

FounderOS — Multi-tenant backend for a founder workspace app. Streaming AI pipeline via ReadableStream.tee(), HMAC-verified Stripe webhooks, Postgres row-level security with an isolated admin service-role client. Next.js TypeScript PostgreSQL (RLS) Stripe GPT-4o — GitHub

Anchor — Offline-first notes with conflict-free multi-device sync. Every keystroke persisted to IndexedDB as a Yjs CRDT operation before any network call — the same replication strategy behind Figma and Notion. Yjs (CRDTs) Tiptap/ProseMirror IndexedDB y-webrtc y-websocket — GitHub
