Key Strengths

  • Shipped end-to-end RAG chat agent (benchmarks, backend, infra, frontend) for Vertex; ingested 2000+ pages and reduced support tickets ~40% in pilot
  • Strong user/workflow-driven product decisions (embedded assistant into desktop app to fit scientist workflows vs web chatbot)
  • Built and operated high-scale financial automation systems at Amazon (handled ~$6B annual expense automation; reduced month-end close costs by ~$20M annually)
  • Production-grade API/service design (auth via IAM/SigV4, versioning, structured error contracts, idempotency, layered architecture)
  • Reliability and operability focus (tests, observability, alarms, canary rollouts)
  • Database and performance optimization (pgvector similarity search, indexing/denormalization/partitioning; improved reconciliation latency ~35%)
  • Led end-to-end incident response for quarter-end scaling spike (DB CPU saturation) and stabilized via query/index tuning and read replicas
