At D'Vinci Group, I built an internal knowledge application with React and TypeScript, connecting its search interface to FastAPI and Supabase Postgres. I also developed a retrieval API with LangChain and Postgres vector search to reduce manual lookups.

At Accenture, I developed Node.js services and REST and GraphQL APIs, and designed Airflow pipelines with safeguards for incomplete data. Earlier at Amazon, I built internal workflow automation and supported production operations by investigating failures and contributing fixes.
