Justin Gardiner engineered end-to-end licensing and caseload management features across the ministryofjustice/create-and-vary-a-licence and related repositories, focusing on robust API development, data modeling, and UI/UX refinement. He delivered new endpoints and workflows for licence creation, recall handling, and COM allocation, using TypeScript, Java, and Spring Boot to ensure data integrity and operational reliability. His work included domain event integration, feature flagging, and audit trail enhancements, improving governance and deployment safety. By modernizing dependencies, refining access control, and aligning UI with business processes, Justin demonstrated depth in backend and frontend development while addressing security, maintainability, and user experience.

October 2025 delivered substantial end-to-end improvements across licensing workflows, data models, and API surfaces, driving safer licence creation, stronger recall guidance, improved governance, and richer data for reporting. Key outcomes include: (1) a more robust licence creation flow with explicit user confirmation, recall-status visibility, and corrected gate logic; (2) reworked early-release banners and UI messaging for consistent guidance and EPF-2 naming alignment; (3) strengthened licence access control and caseload sorting to show releases chronologically and restrict cross-team access; (4) metadata enrichment for licences (licenceKind and eligibleKind) across caseload and licence records to improve recall decisioning and downstream analytics; and (5) API/data-layer stability improvements, including COM caseload sorting, consolidated recall-related email prompts, and fixes to PRRD post-recall release date handling along with enhanced sentence/recall data structures. The work was delivered across three repositories with frontend, backend, and API/data-model changes, underscoring end-to-end capability.
