September 2025 focused on delivering high-value features, improving data integrity, and stabilizing telemetry across two repos. In hmpps-remand-and-sentencing, consecutive sentence handling was enhanced with UUID-based management, validation, and clearer UI for consecutive details; outcome data caching was introduced to reduce API calls and speed up responses; reference data fetching was consolidated into a single refDataService; UI polish was applied to offence outcomes and expandable sections; validation for mandatory fields on edit-offence was added and save-draft functionality was removed to simplify workflows. These changes improved data accuracy, UI usability, and runtime performance. A related stability fix in hmpps-record-a-recall involved reverting an incompatible Application Insights library upgrade to restore proper configuration. Overall, the month delivered tangible business value through faster, more reliable features and cleaner maintenance.

Month: May 2025 Overview: - Focus: Deliver high-value feature enabling NOMIS synchronization for legacy period lengths and lay groundwork for reliable downstream data flows. Key features delivered: - Legacy Period Length Deletion Endpoint for NOMIS synchronization in ministryofjustice/hmpps-remand-and-sentencing-api. This includes repository method, controller endpoint, and service logic to delete legacy period lengths, updates to LegacyPeriodLength DTO to capture required fields for event generation, and ensures an event is emitted upon deletion for downstream systems. Major bugs fixed: - No major bugs fixed this month. Overall impact and accomplishments: - Enabled end-to-end NOMIS data synchronization by adding a delete endpoint and event emission, improving data integrity, automation, and consistency across remand-and-sentencing workflows. - Reduced manual maintenance and potential for data drift by codifying deletion behavior and event-driven downstream processing. Technologies/skills demonstrated: - Java/Spring Boot REST API development (repository/service/controller layers), DTO evolution, event-driven design, and traceable change management. Demonstrated ability to deliver cohesive feature sets with clear auditability via commit references (e.g., 4515fc38cd0ddee384c76844d5d54f134b1509b0).
