During July 2025, Ca worked on enhancing the thetan-buf module within the WolffunService repository, focusing on cross-platform data contract reliability. They expanded the includePlatforms configuration in Wolffun.Protobuf.asmdef, ensuring Protobuf definitions are consistently compiled and accessible across various development and deployment environments. This approach reduced platform-specific build issues by unifying the assembly definition setup. Ca utilized skills in Unity development and platform configuration, working primarily with JSON and Protobuf technologies. The work addressed the need for seamless data contract integration across platforms, resulting in a more robust build process. The contribution was focused and technically sound, reflecting targeted engineering depth.
