• Prototyped and shipped 5+ full‑stack products end‑to‑end — from system design and data modeling to CI/CD pipelines, observability, and real‑user feedback loops.
• ❖ Engineered a simulated crypto CFD trading engine as an event‑driven microservices system wired through Redis Streams and MongoDB snapshots, so trades replay deterministically, positions survive restarts, and the matching path stays low‑latency under load.
• ❖ Architected an AI RAG knowledge workspace with a worker‑based ingestion pipeline over Redis Streams, KEDA autoscaling on stream lag, co‑located self‑hosted Whisper VMs per worker, and embeddings stored in PostgreSQL/pgvector — cutting third‑party transcription costs to zero.
• ❖ Built a real‑time collaborative whiteboard with a custom Canvas rendering loop, WebSocket room server, delta‑sync protocol, and command‑log undo/redo maintaining smooth 60 FPS multi‑user drawing.
• ❖ Designed a sandboxed code execution engine with containerized isolation, enforced time/memory limits, and a job‑queue orchestrator powering AI code‑interpreter workflows safely at scale.
• ❖ Built a custom TypeScript tool‑calling runner (zero frameworks) that executes domain tools — DB queries, clarification prompts — against live store data, enabling L1 support deflection and data‑aware AI responses embedded directly in storefronts.
