Sarmilan Gunabala worked on the kartverket/backstage-plugin-risk-scorecard-frontend repository, focusing on simplifying and stabilizing the catalog representation within the Backstage plugin. He streamlined the catalog-info.yaml configuration by removing redundant Group and Resource type entries and consolidating component information, which reduced complexity and improved maintainability. Using YAML for configuration management, Sarmilan’s changes made the catalog easier to understand and helped facilitate onboarding for new developers. The work was delivered through a collaborative code review process and merged as part of a pull request, demonstrating a methodical approach to configuration management and Backstage catalog organization over a focused one-month period.
