Robin Booth developed and enhanced core features for the ministryofjustice/hmpps-approved-premises-api, focusing on the space booking lifecycle, data integrity, and operational visibility. Over four months, Robin delivered APIs for booking timelines, non-arrival tracking, and status management, while refactoring legacy code and strengthening concurrency controls. Using Kotlin, Java, and SQL, Robin applied domain-driven design and event-driven architecture to model booking events, optimize queries, and enforce validation logic. The work included integrating booking data with dashboards and UI, improving search precision, and ensuring robust data import processes. Robin’s contributions demonstrated depth in backend development, system design, and reliable data handling.

January 2025: Delivered two key API improvements in ministryofjustice/hmpps-approved-premises-api focused on payload efficiency and data import resilience. These changes reduce payload size, improve data quality, and enhance integration reliability with downstream systems.

November 2024 focused on maturing the space booking lifecycle, strengthening data integrity, and improving analytics for the Approved Premises API. Key capabilities delivered include a new Cas1 Space Booking Non-Arrival API with migration and domain events, enhanced departure management with parent-child departure reasons, robust concurrency controls to prevent duplicate or conflicting bookings, and deeper integration with placement requests and dashboards. These changes deliver concrete business value: accurate booking state, reliable reporting, safer user operations, and improved lifecycle visibility across the Cas1 Space Booking flow.

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).
