Andrewjohnysjustice
Worked on the ministryofjustice/laa-data-claims-api repository, delivering features and fixes that improved data integrity, reporting accuracy, and workflow reliability. Over four months, built end-to-end visibility for assessed totals at the submission level, enhanced CSV and YAML exports with new assessment fields, and implemented a robust claim amendment storage model using PostgreSQL and JSONB. Applied version-based concurrency controls and strengthened integration testing with JUnit and Spring Boot, ensuring reliable data handling under concurrent edits. Addressed critical bugs in claim retrieval logic, updated deprecated joins, and maintained high code quality through comprehensive test coverage and consistent environment alignment using Flyway migrations.

Jun 1, 2026June 2026: Delivered a hardened Claims Amendment Storage Model and concurrency enhancements for laa-data-claims-api. Implemented an immutable amendment audit trail with a new storage table and foreign key relationships to preserve historical accuracy, and migrated ledger history to support the 'Latest Wins' approach. Introduced native JSONB storage for audit snapshots to safeguard large payloads and support efficient queries. Applied version-based concurrency controls to prevent data overwrites in high-concurrency edits. Seeded standardized reference data and metadata via Flyway migrations to ensure environment consistency, and built a production-grade integration test suite (ClaimAmendmentStorageIntegrationTest.java) using Postgres 18.3 and Testcontainers. All changes were delivered through Flyway migrations (V39/V40) and supported by robust testing and environment alignment.
