David Thompson engineered robust features and stability improvements across the hmcts/darts-portal and hmcts/darts-api repositories, focusing on secure access control, data integrity, and developer experience. He delivered enhancements such as on-demand portal deployments, refined authentication flows, and resilient session management, leveraging technologies like Angular, Java, and Kubernetes. David applied CI/CD automation, SQL scripting, and integration testing to streamline deployments and ensure reliable workflows. His work addressed complex requirements including role-based access, accessibility, and error handling, resulting in more maintainable codebases and smoother user experiences. The depth of his contributions reflects a strong command of backend and frontend engineering practices.

In August 2025, hmcts/darts-api delivered a focused bug-fix/enhancement to user access error handling. Refactored authentication/authorization error handling to distinguish between 401 Unauthorized and 403 Forbidden responses, covering scenarios where a user is not found or is inactive. This improved API response clarity, security posture, and client UX, reducing ambiguous errors and support tickets. Linked to DMP-5162 (Better differentiate between 403 and 401 errors) with commit 6afba99805a2998e0d0a25b16839169b689e2a14. Impact: more reliable auth flows and easier downstream integrations.
