Apr 1, 2026April 2026 - navikt/testnorge: Key focus on robustness and non-blocking scalability. Delivered a Reactive PDL Manager Architecture Overhaul, enabling non-blocking security and database access (Reactive security, R2DBC) and returning Mono/Flux from service methods, improving throughput and responsiveness. Fixed critical data integrity and export reliability issues with production impact: MatrikkelId datatype corrected from String to Long to prevent 500 errors in address queries; Excel export robustness improved with enhanced error handling, batching, and tests (covers various failure scenarios and improves observability). These changes reduce runtime errors, improve user experience, and position the codebase for scalable growth. Technologies/skills demonstrated include reactive programming (Mono/Flux), R2DBC, reactive security, improved logging/observability, and test coverage.
