During December 2024, João Silva developed a user story deletion feature for the FEUP-MEIC-DS-2024-25/ai4sd repository, focusing on improving backlog hygiene and data integrity. He implemented a handleDelete function in JavaScript using React, enabling safe removal of user stories from local state and automatic re-indexing of the backlog. The feature included a user-friendly delete button with a trash icon, streamlining the story lifecycle and reducing manual cleanup. João’s work demonstrated proficiency in frontend development, state management, and UI integration, delivering a targeted solution that addressed stale backlog items and enhanced the accuracy of project tracking without introducing bugs.
