October 2025 monthly summary for NHSDigital development teams. Focused on delivering secure, scalable, and cost-efficient enhancements across prescription-related services, with emphasis on data integrity and operational resilience.

September 2025 monthly summary focused on delivering reliability, maintainability, and observable business value across four NHSDigital repositories. Key investments this month targeted secure configuration, robust message processing, build stability, and improved observability to support scalable operations. Key features delivered and improvements: - NHSDigital/electronic-prescription-service-account-resources: clarified NHS Notify App ID secret naming and enforced consistent configuration to reduce misconfiguration risk; updated Dependabot cadence to weekly and capped open PRs to improve maintenance throughput. - NHSDigital/eps-prescription-status-update-api: enhanced NHS Notify Lambda with Application ID signing, refined error handling, payload management, improved HTTP retry/backoff, and diagnostics; fixed a batch request issue; introduced rollback on failed downstream SQS notifications and conditional PSU deletion to preserve data integrity. - NHSDigital/electronic-prescription-service-clinical-prescription-tracker: stabilized build and dependency management by aligning dependabot cadence and updating the Dockerfile to use netcat-traditional for consistent environments. - NHSDigital/prescriptionsforpatients: added application name log enrichment to improve traceability across request flows. Major bugs fixed and reliability improvements: - Fixed cooldown logic in the notification processor to honor the maximum relevant timestamp, preventing excessive patient notifications. - Corrected a silly mistake in notify batch request handling and addressed Axios retry with exponential backoff for more reliable retries. - Data integrity improvements in the PSU flow to ensure consistent state during downstream failures. Overall impact and business value: - Reduced risk of misconfiguration and notification spam; improved traceability and observability; more predictable maintenance windows; and more stable deployment environments enabling faster iteration and safer changes in production.

Month: 2025-08 — Delivered targeted testing capabilities, enhanced notify integrations, and improved API resilience across three repos. Key features include NHS number-based test triggers in prescriptionsforpatients and ODS code extraction logging in the notify integration. In eps-prescription-status-update-api, callback processing was hardened with clear separation of channel vs message updates, optional name header support, and robust error handling. Duplicate notifications were prevented by comparing current vs previous statuses, and backend scalability was improved via auto-scaling of the notification state GSI and removal of an unused table. The sandbox enforcement for the Try It button in the electronic-prescription-service-api ensures consistent testing environments.

July 2025 monthly summary focusing on stability, security, observability, and testability across critical NHS Digital APIs. Deliveries span multiple repos, emphasizing business value through secure access, reliable operation, and streamlined release processes.

June 2025 monthly summary for NHSDigital EP projects focused on security posture, reliability, and developer productivity across three repositories. Delivered features to reduce maintenance overhead, strengthen secrets handling, and consolidate NHS Notify integration with robust observability and timeout controls. Implemented a critical SQS error handling fix to ensure proper failure signaling and message cleanliness. The work enhanced business value through lower operational risk, improved system reliability, and clearer operational visibility. Technologies demonstrated include serverless architectures (Lambda, SQS, DynamoDB), IAM least-privilege and role-based access, secrets management, feature toggles, monitoring, and parameter management.

May 2025 monthly summary focusing on feature delivery and reliability improvements across two repositories: eps-prescription-status-update-api and account-resources. Delivered substantial enhancements to the notification pipeline, improved data modeling and indexing for faster queries, and added NHS Notify integration secrets. Implemented robust DB migrations to stabilize state and deployed configuration changes with environment-specific secrets management. The month also demonstrated strong AWS-centric capabilities, security-conscious configuration management, and a clear business-value impact through more reliable patient communications and streamlined secrets handling.

April 2025: Key business outcomes across EPS UI, API, and resources. Accessibility and navigation improvements, richer prescription details, reliable notification flows, and stable builds. Notables include: WCAG-compliant label-input fix in the eps-prescription-tracker-ui; tabbed Prescription list UI for current/past/future with routing/data handling updates; SiteDetailsCards component for prescription details page to surface prescriber/dispenser data; end-to-end Prescription Status Notification System using EventBridge, Lambda, SQS, and DynamoDB with deduplication to ensure a single notification per patient per site within 5 minutes; and a build-stability fix via a TypeScript typing fix in the session service to restore builds. Security/infra improvements include updating secret scanning patterns and adding IAM permission for generating a random salt for PSU notifications. Overall impact: improved accessibility, navigation, data visibility, patient communications, and deployment reliability.

March 2025 monthly summary focusing on delivering business value through platform improvements, authentication enhancements, and UI/UX refinements across API and UI components. Emphasis on security, reliability, and developer experience. The work enabled tighter integration, faster secure deployments, and improved user flows for prescription and patient data.

February 2025 monthly summary for NHSD Digital development teams, focusing on delivering resilient APIs, enhanced user experience, and automated testing coverage across two repositories. Significant migration and feature work in the eps-prescription-tracker-ui, alongside a new regression testing workflow in the clinical-prescription-tracker to strengthen release quality and speed.

January 2025: Delivered targeted API documentation improvements, data integrity fixes, and user-facing RBAC/logout enhancements across eps-prescription-status-update-api, electronic-prescription-service-api, and eps-prescription-tracker-ui. Key achievements include clarifying the EPS API audience in OpenAPI specs, fixing decimal parsing and GP data handling, validating telecom rules and reimbursement formats, and implementing logout and role-management UX. These changes reduce risk for integrations, improve data quality, and strengthen security and access controls, while laying groundwork for backend role integration.

December 2024 performance summary focusing on delivering business value through security, quality, and maintainability improvements across two NHSDigital repos. Key outcomes include standardized CI/CD and QA across EPS projects, robust authentication with AWS Cognito and unified token handling, and role-based access controls integrated into the UI and APIs. These efforts reduced maintenance overhead, improved security posture, and accelerated time-to-value for critical features.

Monthly overview for 2024-11: Implemented security-focused improvements in the NHSDigital/prescriptionsforpatients repo by delivering Secret Scanning and Pre-commit Hook Integration. This included adding a .gitallowed pattern, enabling the git-secrets pre-commit hook, and updating the quality checks workflow to a newer GitHub Actions version. These changes enhance code security, enforce best practices at commit time, and improve CI reliability.
