In February 2026, Yuwatinyi developed the Working Days Command Processing System for the openMF/fineract repository, focusing on backend enhancements using Java and the Spring Framework. The project introduced configurable working days management, including new REST API endpoints for retrieving and modifying scheduling data. Yuwatinyi updated the working days configuration and ensured reliability by fixing command base tests, supporting accurate scheduling and payroll alignment. The work established a scalable foundation for regulatory compliance across deployments, with careful attention to database management and extensibility. This feature laid the groundwork for future enhancements by improving configuration visibility and expanding the API surface.
