During a two-month period, Ziyu Chen enhanced build stability and server reliability across eesast/web and eesast/THUAI8. On eesast/web, Chen refactored dependency management using JavaScript and Yarn, ensuring a consistent @antv/g2 version by centralizing resolution in yarn.lock and aligning related packages to prevent conflicts, which improved CI/CD reliability. For eesast/THUAI8, Chen focused on configuration and game server management with C# and shell scripting, fixing run.sh issues, exposing server startup status, and updating default gameplay parameters for consistency. The work demonstrated depth in configuration and dependency management, addressing version drift and startup reliability without introducing new bugs.
