During March 2025, Yichen Zhang developed a portfolio analysis and backtest visualization feature for the GAOCheryl/QF5214_2025_G8 repository. Leveraging Python for backtesting logic and HTML for front-end display, Yichen scaffolded a new module to process and visualize trading strategy performance. The work integrated portfolio analytics directly into the main user interface, streamlining access to data-driven insights for users. By focusing on data visualization and front-end development, Yichen established a foundation for scalable analytics and informed trading decisions. Although the project was in its early stages, the delivered feature provided essential groundwork for future enhancements in quantitative finance applications.
