Emil Kalstø worked on the navikt/pensjon-verdande repository, focusing on deprecating and removing the Klager til kabal and Anker til kabal batch processing features. He eliminated related UI components and routes, streamlining the migration tooling and reducing long-term maintenance overhead. Using React and Remix with both JavaScript and TypeScript, Emil ensured the codebase was simplified and obsolete workflows were fully removed. His work included preparing documentation and release notes to clarify the changes for future development. The depth of the work lay in carefully disentangling legacy features, resulting in a cleaner, more maintainable frontend architecture for the project.
