PROFILE
Sam Cappleman-lynes
Sam Cappleman-Lynes developed and enhanced backend services for the communitiesuk/eip-ero-print-api and eip-ero-ems-integration-api repositories, focusing on scalable document delivery and API security. He refactored AED PDF generation to serve files directly from AWS S3 using pre-signed URLs, reducing API server load and streamlining client access. Sam also strengthened API Gateway security by removing internal-only endpoints and updating the OpenAPI specification, minimizing external exposure. His work included implementing new admin workflows and refining access controls, leveraging Java, Spring Boot, and integration testing. The solutions demonstrated depth in backend architecture, cloud integration, and secure API design for maintainable, scalable systems.
