Worked on the ministryofjustice/laa-submit-crime-forms repository, delivering features that improved validation, data integrity, and cross-service traceability. Focused on backend development using Ruby on Rails, RSpec, and YAML, the work included implementing robust numeric and item-type validations, enhancing error handling, and refining dummy data generation for realistic testing. Introduced privacy controls through audit log redaction and strengthened bulk submission workflows with state management and request ID propagation. Upgraded dependencies and improved DevOps practices, including Kubernetes and security configuration. The technical approach emphasized maintainability, test-driven development, and user experience, resulting in more reliable submissions and streamlined debugging across distributed services.
