During December 2025, Li Weizhi developed a user class management feature for the eesast/web repository, focusing on enhancing the profile page’s data integrity and user experience. He implemented a department-filtered class selection dropdown, integrating GraphQL for dynamic data fetching and ensuring the UI consistently reflected user selections. Working primarily with React, TypeScript, and JavaScript, Li addressed a scholarship class bug that previously caused misclassification, thereby improving data consistency across the platform. His contributions included updating GraphQL typings and the data layer to support type-safe operations, demonstrating a solid grasp of front-end development and robust data management within a short timeframe.
