Developed and integrated a Catalog Creator Plugin for the kartverket.dev repository, focusing on expanding catalog capabilities through a modular, plugin-based architecture. The work involved wiring routes, managing dependencies, and updating registrations to ensure the new catalog creation feature was both accessible and functional within the application. Leveraging skills in Backstage Plugin Development, React, and TypeScript, the developer established a maintainable foundation for future enhancements such as catalog templates and publisher flows. The integration was thoroughly documented to support ongoing maintenance, and the cycle prioritized feature delivery and workflow reliability, with no major bugs reported or fixed during this period.
