Vae Wonna developed and refined payment processing, deadline management, and user communication features for the Opetushallitus/ataru repository over eight months. Leveraging Clojure, ClojureScript, and SQL, Vae implemented automated payment status workflows, centralized deadline logic, and robust exemption handling, improving data integrity and maintainability across subsystems. Their work included overhauling email templates, enhancing UI feedback, and introducing bulk inactivation APIs, all while strengthening test coverage and observability. By encapsulating deadline logic in a dedicated service and optimizing backend queries, Vae reduced cross-module coupling and operational risk, delivering maintainable, business-compliant solutions that improved reliability and user experience for complex application flows.
