Worked on the navikt/aap-brev repository to enhance backend reliability and prepare for future compliance features. Focused on standardizing MDC logging across API endpoints and job processors using Kotlin and Java, replacing hardcoded keys with a centralized enum to streamline debugging and reduce operational risk. Introduced new data model fields to scaffold support for upcoming PDF letter signature capabilities, ensuring the system is ready for future integration without impacting current production processes. Emphasized maintainability and observability by improving logging practices and laying the groundwork for compliance workflows, leveraging skills in API development, backend engineering, and debugging throughout the project.
