• Delivered React and Next.js product features for customer-facing and internal workflows while coordinating user flows, API contracts, data requirements, and release readiness across the stack. • Architected and led REST and GraphQL API development in Node.js across shopping, inventory, payments, notifications, and reporting workflows, improving service modularity and reducing client over-fetching by approximately 30%. • Used Claude Code, Codex, and Cursor to accelerate feature implementation, refactor legacy modules, debug production issues, and scaffold tests while maintaining human review over final code quality. • Owned AWS infrastructure across EC2, S3, and RDS and automated staging and production delivery with GitHub Actions and Jenkins, enabling zero-downtime deployments. • Raised automated test coverage from near zero to more than 70% by introducing Jest unit and integration tests across a microservices architecture. • Diagnosed critical production incidents across application and infrastructure layers and shipped fixes through established CI/CD workflows
