Feb 1, 2025February 2025 performance summary for NHSDigital/personal-demographics-service-api. Delivered substantial Coverage API documentation and specification improvements, consolidating OpenAPI updates and adding robust guidance for JSON Patch updates, sandbox testing scenarios, mandatory EHIC fields, terminology alignment, superseded record handling, and sandbox/testing resources to strengthen developer experience and data integrity. Implemented targeted data model and validation refinements across the API, including versioning schema adjustments and a shift from patient-record-centric descriptions to coverage-details descriptions. Added and reorganized sandbox test scenarios for get-coverage and post-coverage, and re-linked the Postman collection to streamline onboarding. Ensured product-review alignment by clarifying use-case driven content and EHIC data handling."

Jan 1, 2025January 2025 performance summary for NHSDigital/personal-demographics-service-api: Delivered key features and a major data-quality fix that improve data integrity and developer experience. Delivered three outcomes: data validation clarity for patient contact points, a new get-coverage endpoint with superseded-record handling, and expanded Coverage API documentation including versioning and ETag-based concurrency. These workstreams reduce risk of duplicates, enable safer EHIC data retrieval, and provide clearer integration guidance. Result: higher data quality, better API reliability, and more maintainable docs. Technologies/skills demonstrated: API design, REST, data validation, schema clarity, concurrency control with ETag, and comprehensive docs.
