Worked on the kartverket/backstage-plugin-risk-scorecard-frontend and backend repositories to deliver a risk analysis platform supporting both frontend workflows and backend data persistence. Developed an in-memory risk index with scheduled refresh and integrated it with the catalog database, enabling risk assessment capabilities for users. Addressed authentication reliability by fixing cross-tab GitHub token refresh, ensuring consistent user sessions. Simplified the difference feature contract for improved data access and developer experience. Introduced RiSc Schema Version 5.3, adding an optional metadata field to support schema evolution. Utilized Kotlin, TypeScript, and JSON schema design, focusing on robust API development and plugin integration throughout.
