Simon Payne contributed to the communitiesuk/eip-ero-ems-integration-api repository by building and enhancing backend features focused on data governance, integration reliability, and test modernization. He developed an SQS-based data removal workflow, implementing resilient error handling and context-aware logging using Kotlin and Spring Boot. Simon modernized the testing framework by replacing legacy Cucumber tests with integration tests, externalizing test data for maintainability, and improving CI feedback. He also upgraded the EMS integration API, consolidated OpenAPI definitions, and stabilized tests with LocalStack fixes. His work addressed integration fragility, improved data accuracy, and strengthened operational clarity, demonstrating depth in backend and DevOps engineering.

March 2025: Enhanced EMS Integration API and data model to improve reliability and observability, upgraded Spring Boot, merged OpenAPI definitions, and stabilized tests with LocalStack fixes. Fixed an SQS routing issue via environment variable naming corrections and added explicit typing for EMS_status when persisting data from SQS. These changes reduce integration fragility, improve data accuracy, and accelerate production readiness across the EMS integration stack.

Monthly summary for 2024-11: Delivered a new SQS-based data removal workflow for application integration data in the eip-ero-ems-integration-api, including a message listener, service logic to remove data for both postal and proxy applications, and an OpenAPI specification. Implemented resilient error handling for not-found applications and missing EMS status, and enhanced logging to reflect the processing context (postal vs proxy). This work improves data governance, enables automated cleanup, and strengthens observability and operational clarity.
