Worked on the NHSDigital/ftrs-directory-of-services repository to deliver a robust data migration platform with enhanced observability and governance. Developed feature-flag-driven workflows for controlled data migration, enabling selective execution and safer triage code migrations. Enhanced the platform by integrating Splunk for richer telemetry, implementing a health-check dashboard, and improving error handling and logging. Refactored the data model to normalize organization types and simplify endpoint validation, improving data integrity and migration reliability. Utilized Python, AWS Lambda, and Terraform to build scalable backend solutions, focusing on infrastructure as code, monitoring, and unit testing to ensure resilient deployments and maintainable migration processes.

Mar 1, 2026Monthly summary for 2026-03 for NHSDigital/ftrs-directory-of-services. This month focused on delivering a robust data migration platform with enhanced observability and governance, plus extensions to pharmacy organization, endpoints, and data model cleanup. Key outcomes include migrating contraception pharmacy services, improved error handling and logging, richer telemetry via Splunk, a health-check dashboard for the migration pipeline, and a feature-flag-driven governance model for pharmacy endpoints. Data model cleanup removed the EndpointPayloadType enum and endpoint type validation to improve migration reliability and data integrity. These results strengthen business readiness for data migrations and enable safer, observable operations across the platform.
