PROFILE

Sam Cappleman-lynes

Worked on the communitiesuk/eip-ero-print-api and eip-ero-ems-integration-api repositories, delivering features focused on secure, scalable document delivery and robust API governance. Implemented a workflow to serve Anonymous Elector Document PDFs via AWS S3 pre-signed URLs, reducing backend load and streamlining client access. Enhanced API security by removing internal-only endpoints, updating OpenAPI specifications, and introducing authentication for sensitive statistics endpoints. Refactored admin workflows to support pending EMS downloads with improved access controls. Used Java, Kotlin, and Spring Boot to build and test RESTful APIs, emphasizing integration testing, cloud service integration, and compliance with evolving security and data governance requirements.
