Mar 1, 2026

March 2026 Monthly Summary: Implemented production-ready PDA defaults and configurability across environments, enabling PDA by default in production with a configurable effective date to improve data integrity and user experience. Addressed UAT data issues by supplying an effectiveDate and aligning naming conventions, complemented by targeted tests to ensure data consistency. Strengthened CI/CD and deployment reliability: aligned Helm environment variable names with the values file and pinned the end-to-end test configuration version to a stable baseline, reducing flaky deployments and maintenance risk. Overall impact: reduced data discrepancies, more predictable releases, and smoother testing across environments. Technologies and skills demonstrated: Kubernetes/Helm, CI/CD discipline, test data management, and cross-team collaboration.

October 2024 — ministryofjustice/hmpps-approved-premises-api Key features delivered: - Booking Timeline and Keyworker Assignment Events: Introduced a timeline feature for space bookings (API returns a list of timeline events), added retrieval by booking ID, and updated the timeline query to filter by spaceBooking. Also introduced a domain event for when a keyworker is assigned to a booking, with updates to configuration, controller logic, domain event descriptions, and service implementations to enable tracking and narrative of keyworker assignments. Major bugs fixed: - No critical bugs reported in this period; primary focus was feature development and enabling better traceability and auditability of bookings. Overall impact and accomplishments: - Improved scheduling visibility and auditability for space bookings, enabling faster decision-making and improved compliance reporting. - Enhanced ability to track and describe keyworker assignments, supporting operational coordination and governance. Technologies/skills demonstrated: - API design and evolution (timeline endpoints), domain-driven event modeling, and event narrators. - Controller, service, and configuration updates to support new features. - Query parameterization (spaceBookingId) for precise data retrieval and improved performance. - Clear commit-level traceability for feature delivery (e72f07adb04080e3a3432392f18e2ca3cac39607; 67d641b41fe067825803c83ba3b879b860439142).
