About

Software engineer with experience at Amazon and Agora building end-to-end systems: a knowledge-base AI chatbot (React/TypeScript UI + retrieval/response backend + Docker deployment) and an internal approval governance platform using AWS Step Functions and DynamoDB. Emphasizes fast iteration without sacrificing trust via feature-flag rollouts, citation-required answers, abstention on low-confidence retrieval, regression query sets, and strong observability (request IDs, structured logs, latency/error monitoring).

Key Strengths

  • End-to-end ownership of customer-facing AI chatbot (frontend, backend, deployment)
  • Rapid iteration with quality guardrails (feature flags, citations, abstain-on-low-confidence, regression set, monitoring)
  • Strong frontend architecture for responsiveness (streaming UI; separation of chat state vs retrieval metadata; typed API layer)
  • Reliable distributed workflow design at scale (Step Functions, idempotency, retries/timeouts, conditional writes)
  • Observability-driven debugging (request IDs, structured logs, monitoring for latency/errors)
  • Built and drove adoption of internal governance/approval tooling with auditability and measurable ops improvements (throughput, turnaround time, reduced manual touchpoints)
