June 2026 (hmcts/opal-fines-service): Delivered two major features with strong business value and reinforced API reliability through comprehensive testing and robust data mappings. Implemented payment terms controls to support configurable billing and enhanced result handling; introduced a fully-fledged defendant account history API with filtering, mapping, and integration tests. Demonstrated strong ownership of end-to-end delivery, security considerations, and scalable design.

May 2026 focused on delivering secure, test‑driven enhancements to the Opal Fines and Draft Account APIs, improving business value through better security, reliability, and data integrity. Highlights include a feature‑flagged Minor Creditor PATCH flow with proper versioning, BACS-based GET permissions, and extensive integration tests; rollout support via shared constants and opal-common-lib alignment; legacy PATCH compatibility improvements; and a Draft Account API cleanup removing timeline_data, strengthened JSON schemas, 400‑response tests, and clock‑based time handling for deterministic behavior in tests and production.

April 2026 monthly summary for hmcts/opal-fines-service. Delivered two major feature sets: Remove enforcement holds on defendant accounts with new endpoints, DTOs, and tests, enabling authorized users to lift holds securely; and Account validation and security enhancements, enforcing time_of_issue HH:mm format and valid draft account language codes (EN/CY) with tightened minor creditor patch permissions. The work included extensive test stabilization and quality improvements: replacing mocks with real DTOs, strengthening service/integration tests, and achieving checkstyle compliance. These changes improve operational efficiency, data integrity, and security, while reducing risk of incorrect holds or invalid payouts. Tech contributions span REST API design, DTO-driven service layer, JSON schema validation, deterministic tests via wired Clock bean, and dependency updates (Lombok v1.18.46, Redis tag).
