Fullstack on the Lens team — joined pre-launch, now serving global users. End-to-end features across the AWS stack: real-time WebSockets, server-side pagination, geospatial risk analysis, and i18n for the Japanese market. React Router v7 migration and React Compiler performance work.
Fullstack developer on the Lens team, working on the platform Amazon uses to evaluate and acquire new sites — joined before launch, now serving global users. Across the AWS stack with React, TypeScript, and PostgreSQL.
- Developed an instinct for performance work: built a small Chrome DevTools Protocol profiler so regressions became measurable instead of anecdotal, and applied the same lens to the React Router v7 migration and React Compiler adoption
- Learned to ship in ambiguity — owning end-to-end features (real-time WebSocket flows, server-side pagination, geospatial risk analysis) on a fast-moving product where requirements evolve as we learn
- Grew as an architect: designed a composite picklist service across three data sources, learning when caching pays off, when validation belongs at the boundary, and when to keep things boring
- Practiced thinking globally by shipping i18n for the Japanese market — addressing, units, and formatting — which sharpened my sense for how cultural detail compounds in a product
- Sharpened collaboration through code reviews, pairing, and design docs — turning local insights into team-wide patterns
