Sep 1, 2025September 2025: Delivered targeted reporting enhancements and cleanup to the NHSDigital/nhs-notify-reporting platform. Implemented a client-specific filtered reporting dashboard with a new SQL view, updated IAM policies, and Terraform-backed resource provisioning to ensure client data isolation. Added a weekly supplier invoice reporting view, renamed/preserved the monthly reports where appropriate, and configured IAM permissions to enable weekly reporting alongside existing monthly data; also resolved the Proco week-start alignment issue. Introduced the templateid dimension across plan summaries and reporting, with SQL and Terraform updates enabling filtering and aggregation by template IDs. Completed cleanup of deprecated example code and legacy migration artifacts, and refreshed documentation to reflect the current data model, reducing technical debt and improving maintainability. Technologies demonstrated include SQL data modeling, Terraform infrastructure as code, IAM governance, and cross-team scripting.

Aug 1, 2025In August 2025, delivered two features in NHSDigital/nhs-notify-reporting that enhance reporting granularity and delivery diagnostics. Added a templateid field with DB schema changes, ingestion population, and SQL updates to surface template-level performance. Introduced an AWS Athena named query to report PDS cleared failures to diagnose and resolve delivery issues. No explicit bug fixes recorded in this period. These changes enable data-driven decision making, improve visibility into template usage and delivery reliability, and demonstrate proficiency in DB migrations, ingestion pipelines, SQL, and AWS Athena.
