David Sally is a Senior Software Engineer in Oakland with ~9–10 years of experience building full-stack web applications and developer tooling, currently focusing on React, TypeScript, Relay/GraphQL, and Node at Lattice. He has driven end-to-end product work—from early conception through alpha and general release—on complex features like compensation modules and has a track record of improving performance and developer velocity by migrating apps to Next.js and modern build systems. Previously he led engineering at Dictionary.com, modernized legacy stacks at MeUndies and Disney, and built content recommendation and email microservices at MedCircle. An active open-source maintainer, he contributed UI and traversal algorithms to React Sight, a visualization tool with 2,200+ stars that inspects live React component hierarchies. His background in microfluidics and Python-driven hardware testing at Bio‑Rad surfaces an unusual blend of hardware, data analysis, and software engineering discipline. Colleagues would describe him as opinionated about best practices, focused on reducing complexity, and effective at turning messy legacy code into maintainable, high-performance applications.
