PROFILE
Simon Brunning
Over three months, contributed to NHSDigital/eligibility-signposting-api by building and refining a robust eligibility processing backend. Focused on API development and rules engine implementation, the work included integrating AWS services such as DynamoDB and S3, establishing scalable rules storage, and modernizing API design for maintainability and multi-environment deployment. Leveraging Python, TypeScript, and Docker, the developer enhanced test coverage, improved data modeling, and introduced operator-driven rule evaluation with priority handling. Emphasis on code clarity, configuration management, and CI/CD readiness resulted in a stable, well-documented codebase that supports reliable eligibility queries and streamlined developer onboarding across evolving project requirements.

May 1, 2025May 2025 monthly summary for NHSDigital/eligibility-signposting-api focused on reliability, maintainability, and business value. Key features delivered: NVL/default to operators and improved NVL matching with extended OFFSET/date operator support, supported by tests (commits including ELI-236 - Add NVL Default to Operators; non-greedy NVL matching; OFFSET tests; final operator changes). Live Iteration Handling: evaluate only live iterations and add tests for campaigns with no live iteration (commits: 64916156; 62e90f80; 8a5bcfc4). Data Model Simplification and Safety: simplified structures, added cohort_label, ignore unrecognised data, refactor eligibility_rows_builder naming (commits: 27a40f39; c5ca1733; 036d3767; baf6f9c2; 1c5dea97). Eligibility Rules - Filter and Suppression and Rule Priority: implement filter/suppression functionality and refactor/expose calculator with priority evaluation; align tests (commits: 9ef9abfd; 99b2e16e; 0daff15b; 5f1379b2; 18abbf93; 3d7099a2; 08d99460; a3e63b2d; 9afdae76). Testing Enhancements: eligibility rows fixture; cohort/campaign & non-base-eligible tests; enhanced test utilities (commits: 87e632e6; aa21b756; 75c8e210; 7ab18fac; 5377ed2e). Documentation and Maintenance: context diagram in README, missing link fixes, version bumps (commits: 8baefe83; ddbe5e40; 5b072204). API surface and readiness: ELI-204 API path update and subsequent version bumps (commits: 29bc6856; 105df5e9). NHS number faker provider and improved visibility of PersonDetailProvider; added missing gender values (commits: 679961d5; 19a29976).
