SeniorJD Cantrell is a seasoned software engineer with 13 years building full-stack web applications and leading front-end teams from San Francisco. He has driven product and platform work at companies from Trulia to Opendoor and most recently Customer.io, combining hands-on React/GraphQL UI development with API design and light DevOps. JD led design system growth, enforced strict TypeScript and code hygiene, and translated product requests into actionable engineering work as a staff-level front-end architect.
