Worked on the hmislk/hmis repository to enhance the user experience and clarity of delete operations within the backend. Focused on backend development using Java and JSF, the work involved standardizing error messaging across all delete endpoints to ensure that users receive explicit feedback when attempting to delete non-existent resources. By implementing uniform error handling in REST controllers, the changes improved API consistency and maintainability. This approach not only reduced potential user confusion but also facilitated smoother frontend integration by providing clear, actionable responses. The update addressed a key bug, contributing to reduced support queries and a more predictable API interface.
