My key achievements include:EOS Online Services Integration: Integrated the existing EOS Online Services plugin (from UE5) into our game. Fixed numerous bugs in the plugin, enhancing its stability and functionality. Successfully integrated key components such as the party system (lobbies), friends, voice chat, and rich presence.Coherent Gameface Development: Focused on core-tech work, addressing critical crashes and stability issues. Implemented a custom string wrapper around UE5 FString to track its lifetime, preventing crashes. Debugged and resolved an out-of-memory (OOM) crash on PS5 caused by Lottie animation. Collaborated with C++ and frontend teams to provide recommendations and explanations for technical solutions.Azure SignalR Integration: Integrated Azure SignalR on both UE and backend sides to enable real-time communication with our backend.EasyAntiCheat Integration: Performed the integration of EasyAntiCheat into our game. Made the anti-cheat system platform-dependent, enabling it only for PC players to support future cross-play.Through these efforts, I have significantly enhanced the game's stability, performance, and overall user experience, contributing to the successful integration of critical systems and ensuring smooth operation across platforms.
