Apr 1, 20262026-04 monthly summary for Opetushallitus/ataru. Delivered a new Mass Update for Application Processing States feature that enables bulk updates of application states with a responsive UX and backend optimizations. The work includes a loading spinner cue and a persistent modal while the backend processes the request, improving user feedback and reliability during long-running operations. Backend improvements optimize processing by fetching review rows in a single bulk query and applying updates only to applications that match the target state, reducing DB load and update time. The feature also extends coverage to cases where processing-state-review records are missing, enabling state transitions such as KÄSITTELEMÄTTÄ -> KÄSITTELYSSÄ. A new database specification for mass updates was added to formalize and govern the operation.

May 1, 2025May 2025 monthly summary for Opetushallitus/ataru. Key features delivered include a refactor of hakukohde management utilities with added unit test coverage, and an improved Excel export workflow that omits the application fee state column when fees are not required. These changes were supported by new utilities (hakukohde-utils, get-filter-defs-without-payment-obligation) to enhance maintainability and data cleanliness. Major bugs fixed / code quality improvements: applied code review fixes to stabilize the OY-5137 changes related to Excel exports. Overall impact: increased maintainability and testability of hakukohde management logic, cleaner data exports reducing manual data processing, and improved data quality for downstream reporting. The work demonstrates strong skills in unit testing, refactoring, modularization through a utilities namespace, and data export filtering. Top 3-5 achievements: - OY-4946: Unit tests added + helper moved to hakukohde-utils (commit c9701e3a8e479e9d43a74b343dc98aea052804a8) - OY-5137: Cleaner Excel exports when application fees are not required; introduced get-filter-defs-without-payment-obligation (commits 98940ef38bf0efb51372be723c20c9c6f0abad4c, c703cca0d726ca11c101a3d0a520f85b6eee5483) - OY-5137: Code review fixes (commit c703cca0d726ca11c101a3d0a520f85b6eee5483)

Jan 1, 2025January 2025 monthly summary for Opetushallitus/ataru: Delivered role-based data fetching for the application list to ensure correct data retrieval based on user roles. Implemented conditional exclusion of 'lähtökoulu' from API requests when a user holds dual roles 'opo' and 'hak. pal. pääkäyttäjä'. Introduced a new event handler to orchestrate the API call, aligning data access with RBAC requirements. Result: cleaner data, reduced payload, and improved data accuracy for admin users.
