Over three months, Calum McDonnell contributed to HDRUK’s gateway-api and gateway-web repositories, focusing on backend and full stack development using PHP, JavaScript, and TypeScript. He engineered CSV-driven migration and image update tools to streamline data management, implemented robust API endpoints for linkage extraction, and enhanced dataset creation workflows to improve user onboarding. His work included strengthening data integrity through validation, soft deletes, and access checks, as well as stabilizing email notification reliability and CI/CD pipelines. By addressing both user-facing and infrastructure challenges, Calum delivered features and fixes that improved reliability, developer velocity, and the maintainability of complex data workflows.

December 2024 monthly delivery focused on reliability, stability, and developer productivity for HDRUK/gateway-api. Key outcomes include fixes to email notification reliability, a temporary relaxation of sanitization in AliasReplyScanner to unblock workflows, and CI/CD/runtime stabilization to reduce environment flakiness.

October 2024 achievements focused on stabilizing user-facing UX and accelerating data-management workflows across gateway-web and gateway-api. Key navigation and branding issues on the Our Mission and Purpose page were resolved, restoring correct banner rendering and consistent labeling. In the API domain, we delivered multiple tooling improvements: a robust CSV-driven migration tool to assign teams to collections with data integrity checks, unassigned fallbacks, and user-visible progress; a CSV-driven image-link updater with dry-run previews and enhanced logging; and lifecycle improvements including soft deletes for DatasetVersionHasNamedEntities. We also strengthened safety around collection deletion with per-user access checks and added tests to guard against regressions. These efforts reduce manual remediation, improve data integrity, and accelerate content/collection management while maintaining strong auditability and developer velocity.
