During the month, contributed to the navikt/familie-ks-sak repository by developing a new PATCH endpoint within the ForvaltningController, enabling updates to a seeker’s identifier. This feature supports patching merged identifiers and includes an option to verify whether the old identifier is historical relative to the new one, addressing data integrity concerns for merged identities. The implementation focused on minimizing risk and operational overhead by reusing existing code rather than introducing new logic or tests. The work was carried out using Kotlin and Spring Boot, demonstrating skills in API and backend development while streamlining identifier management processes within the service.
