October 2025: No new user-facing features or bug fixes delivered for NHSDigital/communications-manager-api. The month focused on repository governance through a No-Op Commit Audit to improve code hygiene, traceability, and release readiness. The audit confirmed that commit 826d8f2d9b08b825e8d2a7a0d0c760c5601bc864 did not modify code, ensuring no unintended changes were introduced. This work reduces risk and supports faster, safer future feature delivery.

September 2025 monthly highlights for NHSDigital/nhs-notify-supplier-api: Delivered API and data-model improvements to enhance scalability, data richness, and reliability for supplier communications. Key features delivered include: (1) Cursor-based pagination for the Get Letters endpoint with limit (renamed from size), plus supplierId header validation and an extended Letter model with groupId to enable richer data retrieval. (2) Data access refactor to fetch only required attributes, reducing payload size and latency. (3) Sandbox API simplifications and enhanced observability, including removal of cursor and status from listLetters and added logging on get-letters. (4) Quality improvements in tests with corrected descriptions in LetterRepository tests. (5) CI/CD stability improvement by increasing Trivy scan timeout from 5 to 10 minutes, reducing CI failures on large codebases. Overall impact: higher scalability for large datasets, richer data for consumers, improved reliability and observability, and clearer tests that enhance maintainability. Technologies/skills: API design with cursor-based pagination, data modeling, header validation, targeted data access, observability/logging, testing discipline, and CI/CD reliability.

August 2025 focused on delivering measurable business value by enhancing the Get Letters API in the supplier-facing service of NHS Notify. Key work centered on adding supplier-scoped access, status-based filtering, and pagination to improve data retrieval, alongside schema validation and logging to boost data integrity and observability. A major part of the effort was enabling access to the Letters DynamoDB GSI to accelerate queries for supplier-specific letter retrieval, significantly reducing latency for common workflows. This work aligns with CCM-11602 and involved a series of commits that established tests, updated schemas, and exposed the endpoint for production use. Major bugs fixed: No separate high-severity bugs fixed this month beyond the ongoing improvements related to the Get Letters API enhancement. Overall impact and accomplishments: Delivered a robust, scalable API enhancement that improves supplier experience, data quality, and performance; reduced latency for common letter retrieval paths; strengthened observability and maintainability through structured logging and schema validation. Technologies/skills demonstrated: TypeScript/Node.js, Zod for schema validation, DynamoDB (including GSI), AWS Lambda, API design best practices, test-driven development, and enhanced logging for better operability.

2025-07 monthly summary for NHSDigital/communications-manager-api focused on codebase hygiene and maintainability. There were no user-facing features or bug fixes delivered this month; work centered on housekeeping to establish a cleaner baseline and reduce technical debt, enabling faster, safer delivery of future features.
