PROFILE
Joel Luukka
Joel Luukka developed and enhanced backend features for the Opetushallitus/ataru repository, focusing on the TUTU Applications API. He transitioned the applications listing endpoint from GET to POST, enabling efficient handling of large OID sets and enriching application data with ONR person details. Joel improved data traceability by introducing form-level identification within application records and updated data structures and queries to support analytics and debugging. His work emphasized maintainability through code refactoring, expanded integration and unit testing, and removal of obsolete tests. Using Clojure and SQL, Joel delivered robust, test-driven solutions that improved reliability and future extensibility of the service.
