Daniel Soper is a Full Stack Engineer with nine years of experience building user-focused web and cloud services, currently developing React/Redux front-ends and Node.js serverless functions at American Express. He combines a strong applied physics background from UC Santa Cruz with practical expertise in React, React Native, GraphQL, SQL/NoSQL, and payment integrations like Stripe to solve complex UI and backend problems. Past roles show end-to-end ownership—from migrating REST to GraphQL and implementing tokenized account flows to building payments and admin tooling—demonstrating a knack for system migrations and reliable state management. His early work in hardware testing and particle detector research gives him a disciplined, data-driven approach to testing and QA that informs his software craftsmanship. Based in Sacramento, he’s equally comfortable shipping polished front-end experiences and architecting backend services, with a track record of improving internal tooling and developer workflows.
