Sophie Tsai is a Senior Software Engineer with 6 years of experience building performant, user-focused frontends and full-stack integrations, currently at Pipe. She specializes in TypeScript, React, Next.js and GraphQL, and has a track record of improving release velocity and code quality—at Glean she was the top frontend contributor by merged PRs and introduced optimistic updates, skeleton loaders, and request-batching with dataloaders. Sophie pairs strong testing discipline (Jest, Testing Library, Cypress) with practical API experience (REST, gRPC, Apollo, WebSockets) and has integrated services like Plaid, Dwolla, and Shopify in production. Her background in rapid content production and social media growth gives her a knack for shipping polished UX and creative problem solving under tight deadlines. A portfolio-driven builder, she maintains several public projects and a personal site that showcase her end-to-end engineering and product instincts.
