Nilsu developed and enhanced a badge system for user achievements in the bounswe/bounswe2025group3 repository over a two-month period. She implemented backend models, serializers, and REST API views using Python and Django, enabling users to earn, retrieve, and visualize badges based on their activities. Her work included creating scalable endpoints for badge assignment, integrating progress visualization, and refining the badge awarding logic to improve accuracy and support analytics. By focusing on clean API integration and laying the groundwork for future reporting, Nilsu addressed user engagement and motivation, delivering features that support gamification without introducing major bugs or regressions.
