Tristan Agra developed a static leaderboard feature for the BETIS-Fasilkom-UI/BETIS25-FE repository, focusing on frontend improvements using React, Next.js, and TypeScript. He replaced dynamic data fetching with hardcoded student data to enhance reliability and simplify the user experience. Tristan updated the navigation bar to make the new leaderboard view easily accessible, ensuring users could quickly locate and interact with the feature. UI components were adjusted to display static data consistently, addressing potential issues with data loading and improving interface stability. Over the course of one month, his work centered on robust UI development and clear, maintainable code without bug fixes.
