Nancy Dao is a front-end-focused software engineer with six years of experience building scalable, maintainable web applications using React/Redux and Node/Express. She has led revamps of customer-facing interfaces, refactored legacy class components to modern hooks and context, and driven GraphQL migrations to reduce overfetching and latency. Her work spans desktop Electron apps and web UIs, including an open-source API testing tool for streaming protocols (HTTP/2, SSE, WebSockets, gRPC) where she implemented gRPC features and local caching with IndexedDB. She emphasizes performance and observability—profiling with Lighthouse/React Profiler, integrating Sentry, and cutting technical debt by over 85% through disciplined analysis. Based in California, she pairs a pragmatic product mindset with front-end optimization expertise and a track record of making complex tooling more usable for developers. An interesting non-obvious detail: before software she worked clinically as a registered dental hygienist, bringing attention to detail and user empathy into her engineering practice.
Swell: API development tool that enables developers to test endpoints served over streaming technologies including Server-Sent Events (SSE), WebSockets, HTTP2, GraphQL, gRPC, and tRPC..
