Worked on backend development in the navikt/pensjon-etterlatte-felles repository, focusing on improving code quality and simplifying the data model. Addressed a bug by removing the redundant mottattDato field from the Inntektsjustering data class, ensuring the domain model accurately reflected current requirements and reducing unnecessary data handling. This change helped minimize maintenance overhead and lowered the risk of data inconsistencies across related services. The update was implemented in Kotlin, with careful attention to downstream compatibility and integration. The work demonstrated a methodical approach to backend engineering, emphasizing maintainability and alignment with evolving business logic over the course of the month.
