David Edmondson is a Principal Engineer based in Los Angeles with 14 years of experience building full-stack web applications, test automation, and developer tooling. At TrueCar he led frontend architecture work—migrating from REST/Redux to GraphQL, shepherding a Flow-to-TypeScript conversion, and creating a company-wide component library while improving test reliability with Cypress. He pairs a systems-administration and QA background with hands-on engineering across Ruby, JavaScript/TypeScript, Node, Rails and modern frontend stacks, and has an eye for accessibility and documentation that drives team self-sufficiency. An active open-source contributor, his TypeScript and React work includes enhancements to DefinitelyTyped and game UI/features in Bitburner, and his side projects range from Phaser game prototypes to a Koa+Angular full-stack boilerplate. Comfortable translating design and art skills into interactive experiences, he brings a pragmatic, test-driven approach to complex front-end systems and developer workflows.
