Worked on the grafana/mimir repository to address a navigation issue in the web UI when deployed behind a base path. Delivered a bug fix that introduced a resolveBaseURL template helper, ensuring all internal UI links dynamically respect the configured -server.path-prefix. This eliminated hard-coded absolute paths, reducing 404 errors and misrouted links in path-prefix deployments. The solution involved updating frontend templates, integrating the helper throughout the UI, and adding unit tests to verify correct URL resolution. Utilized Go for backend logic and HTML for template updates, demonstrating skills in API development, backend development, and web development within a focused scope.
