Worked on PKUHPC/CraneSched, delivering features and fixes that improved scheduling reliability, build reproducibility, and developer experience. Over ten months, contributed asynchronous batch processing, X11 forwarding for remote graphical tasks, and runtime configuration enhancements, while also addressing build system stability and security hardening. Refactored core modules for maintainability, introduced CI/CD optimizations, and implemented robust test framework RPCs for deterministic test isolation. Leveraged C++, Go, and CMake to streamline backend development, system programming, and build automation. The work emphasized code quality, maintainability, and cross-environment compatibility, enabling faster iteration, safer deployments, and improved observability across the CraneSched codebase.
