Worked on backend development for the nextcloud/cookbook repository, focusing on improving the reliability of recipe image rendering. Addressed a bug where image retrieval would fail if the 'size' parameter was missing in GET requests by implementing a default fallback to the 'full' image size. This PHP-based solution enhanced the robustness of the API, ensuring users consistently receive images even when parameters are incomplete. The change improved user experience by reducing broken image scenarios and streamlined support by minimizing related issues. All modifications were contained in a single, well-documented commit, reflecting disciplined change management and readiness for production deployment.
