Rajaram Nagarajan developed and maintained core features for the ministryofjustice/hmpps-activities-management and related APIs, focusing on data integrity, security, and user experience. He engineered solutions such as centralized attendance management, pay rate history tracking, and adjudication hearing location mapping, leveraging technologies like TypeScript, Java, and Spring Boot. Rajaram improved backend reliability through database migrations, input validation, and audit logging, while also refining frontend flows and UI clarity. His work included API integrations, infrastructure automation with Docker and Helm, and vulnerability mitigation. Across 41 features and 10 bug fixes, Rajaram demonstrated depth in full stack development and robust system design.

October 2025 monthly summary: Delivered critical data integrity and security improvements across HM Prison and Probation Service Activities Management APIs. Key feature delivered: adjudication hearing location mapping enhancement using locationUuid translated to NOMIS location ID via NomisMappingAPIClient, improving accuracy of hearing locations. Major bug fix: UI rendering improvement for allocation start date by ensuring allocateJourney is correctly passed to the view. Security/technique improvement: reduced the JOURNEY_DATA_TOKEN_DURATION from 24 hours to 8 hours across development, pre-production, and production environments, including Helm deployment and server configuration, with tests updated. These changes provide more accurate adjudication data, reduce exposure risk, and improve user experience for allocation workflows. Technologies demonstrated: API integration with Adjudication API and NomisMappingAPIClient, deployment automation with Helm, server configuration, testing updates, and front-end view binding.

Monthly summary for 2025-08 focused on delivering a centralized, maintainable attendance management platform and reducing legacy debt across APIs, with explicit improvements to data integrity, user flows, and testability. Key work spans two repositories: hmpps-activities-management and hmpps-activities-management-api. Key initiatives delivered this month include a major overhaul of attendance journey handling via a central journeyData structure, enabling consistent handling of attendance and activity journeys; enhancement to cancellation flows for single activity sessions; updates to location handling using DPS Location UUIDs for accurate, non-residential location tracking; and targeted testability improvements. In parallel, a cleanup of deprecated migration APIs reduces technical debt and clarifies the API surface, while attendance summaries were augmented to include UUID-based location data to improve reporting fidelity. Value delivered: improved data consistency and maintainability, streamlined user journeys, reduced risk from legacy APIs, and stronger test coverage to support future changes.
