Jan 1, 2026January 2026 (Opetushallitus/jod-yksilo-ui) focused on strengthening data integrity, security, and reliability of the UI data-loading paths. Delivered two high-impact fixes: 1) Occupation Data Integrity and Loader URI Update, ensuring ammattiryhma is a required field and the loader uses the correct URI to fetch job opportunities and user goals; 2) CSRF Middleware Unregistration on Session Expiry, ensuring proper cleanup of CSRF middleware to prevent lingering risk after session expiration. These changes reduce data fetch errors, mitigate security risks, and improve overall user experience and trust in the job matching workflow.

Dec 1, 2025December 2025: Delivered a consent management refactor on Opetushallitus/jod-yksilo-ui to reuse the personal details API endpoint, enabling updates to consent preferences without clearing personal data. Introduced user-facing toggles for data sharing and AI usage to give users finer control over their data. Fixed a regression where updating consent cleared personal details, improving data integrity and user trust. Consolidated endpoints to reduce backend complexity and improve maintainability, laying groundwork for future privacy features.
