Kangkaisen

Kang Kaisen contributed backend and build system enhancements to the crossoverJie/starrocks repository, focusing on cross-platform development and macOS compatibility. Over two months, Kang enabled Apple Silicon support by updating CMake build scripts, introducing macOS-specific tooling, and refining dependency management for third-party libraries such as protobuf and LevelDB. He improved runtime observability by extending query state outputs and strengthened auditability by ensuring submitter IPs were logged for compliance. Using C++, CMake, and shell scripting, Kang’s work reduced build failures, streamlined developer onboarding for Mac users, and improved CI reliability, demonstrating a thorough approach to platform enablement and backend maintainability.
