Alexander Kjeserud developed advanced backend features for navikt/aap-tilgang and navikt/aap-kelvin-komponenter, focusing on scalable authorization and efficient caching. He introduced dynamic authorization parameter resolution and generalized access control for POST endpoints, using Kotlin and Ktor to enable flexible, route-aware security without static configuration. In navikt/aap-kelvin-komponenter, Alexander engineered a proxy-based caching layer with Caffeine, supporting annotation-driven configuration, per-method and global caches, and time-based eviction. His work emphasized robust software design, leveraging Java, dependency injection, and unit testing to ensure maintainability. Across both repositories, Alexander delivered well-documented, extensible solutions that improved security, scalability, and backend performance.

January 2025 highlights for navikt/aap-kelvin-komponenter: Delivered a robust Kelvin Cache System featuring a dynamic proxy-based cache layer built on Caffeine, enabling 2-minute time-based eviction and seamless caching of @Cacheable results. The feature evolved to support a global cache, per-method caches, void/null results, and configurable cache parameters, with a dedicated README for usage and annotation-driven configuration.

Month 2024-11: Delivered generalized access control and flexible authorization logic for POST endpoints in navikt/aap-tilgang. Implemented interfaces and methods, refactored AuthorizedClient.kt to support AvklaringsbehovResolver, and updated JournalpostIdResolver to accept both parameters and request bodies for improved type safety and flexibility. This work establishes a scalable foundation for access governance and future authorization enhancements.
