Emra Meduseljac developed a Shelter Shift Sign-Up System for the oss-slu/shelter_volunteers repository, focusing on improving volunteer scheduling efficiency. Emra refactored the frontend UI using React and JavaScript to display available shifts and enable users to add them to their schedules, streamlining the selection process for volunteers. The work included updating data handling and modeling to support the new shift workflow, as well as enhancing test coverage to ensure reliability and maintainability. This feature reduced manual coordination and improved shift coverage across shelters, laying the foundation for scalable, shift-based volunteering operations. The project demonstrated depth in frontend development and workflow integration.
