Mark Dathorne contributed to the hmcts/hmc-hmi-outbound-adapter and hmcts/hmc-cft-hearing-service repositories, focusing on backend reliability, observability, and deployment stability. He engineered batch processing and robust error handling for pending requests, modernized date-time handling with Java and SQL, and improved audit logging for traceability. Mark refactored APIs, enhanced test coverage using Mockito, and standardized repository access with Helm and OCI registries. His work included SQL optimization, code cleanup, and dependency upgrades, reducing manual intervention and improving maintainability. By addressing both feature delivery and bug resolution, Mark demonstrated depth in backend development, system integration, and DevOps practices across Java-based services.

March 2025 focused on reliability, observability, and maintainability for the hmcts/hmc-hmi-outbound-adapter. Delivered targeted bug fixes and feature-enhancements with strong test coverage and code hygiene improvements. Key outcomes include robust exception handling for non-retryable errors, enhanced audit logging and triage detail capture, and a new hearing request constant with accompanying tests. Also completed import cleanups and standardized logging formatting to improve maintainability and readability. These changes reduce downtime in message processing, improve traceability for audits, and position the codebase for easier future changes while meeting quality/gate requirements.
