January 2026: Delivered targeted simplifications and stability improvements across two repos. In City-of-Helsinki/notification-service-api, simplified the admin UI by removing the AuditLogEntryAdmin class, reducing complexity and focusing on core audit functionality. In City-of-Helsinki/yjdh, fixed Ahjo integration tests parameterization by correcting the request type, and cleaned up dependencies by moving uwsgi to main requirements for the Benefit service. These changes improve maintainability, test reliability, and deployment consistency.
