PROFILE
Daniel Humphreys
Over a two-month period, contributed to the ministryofjustice/hmpps-approved-premises-api by delivering eleven features focused on reliability, maintainability, and data quality. Developed a unified API error handling framework using Kotlin and Spring, standardizing error responses and improving debugging efficiency. Enhanced test infrastructure and upgraded dependencies such as Guava and JaVers-core to ensure robust integration and unit testing. Improved data consistency by migrating report date fields to LocalDate and implementing postcode normalization and validation. Extended business logic for cohort handling and unarchive windows, while also refining type definitions in TypeScript for the community-accommodation-tier-2-ui to strengthen data model safety.

Apr 1, 2026April 2026: Delivered a major reliability and maintainability sprint for ministryofjustice/hmpps-approved-premises-api. Implemented a unified API error framework (ApiProblem, UnauthenticatedProblem) with standardized ResponseEntity error responses, enhanced tests and documentation; upgraded core libs (Guava 33.5.0-jre and JaVers-core 7.10.0); improved date handling by adopting LocalDate for report fields; strengthened test infrastructure for more reliable DomainEventEntity handling; refined the problem-detail model (InvalidParamsProblemDetail) with extended invalid-params support. Result: consistent error surfaces across clients, reduced debugging time, and improved release quality.
