Cenar migrated the caching backend for navikt/bidrag-reisekostnad-ui from Redis to Valkey, focusing on reducing external dependencies and improving maintainability. The work involved updating TypeScript code to adapt caching logic, revising Docker configurations, and modifying YAML-based environment variables to support the new backend. By ensuring feature parity and minimal production disruption, Cenar enabled the application to scale more easily in the future. The migration included comprehensive documentation updates to guide future development and operations. This project demonstrated depth in backend development, caching strategies, and DevOps practices, with all changes delivered in a single, well-coordinated commit over one month.
