- Engineering hire #3 on an AI executive-assistant product; shipped full-stack features end-to-end on Node.js + React.
- Built a distributed message-queue ingestion pipeline (RabbitMQ quorum queues, publisher confirms, Redis idempotent dedupe, DLQ + retries) with zero dropped events under load.
- Architected a multi-tier cache (in-memory → Redis → source API) with Redis Pub/Sub cross-instance invalidation, cutting p95 read latency from >10s to <500ms.
- Built the AI generation pipeline: GPT-4 drafts conditioned on user writing style, RAG over Pinecone, and CRM/calendar context injection; migrated LLM provider for ~20x cost reduction.
- Delivered full Microsoft Graph parity (OAuth, webhooks, refresh-token worker) for an originally Google-only product.
- Built an SSE real-time sync layer over Redis Pub/Sub with reconnect, event dedup, and mutation cooldowns.
