Worked on the kvcache-ai/Mooncake repository to improve build reliability and network resilience for Go module fetches. Addressed a compilation error in the S3SnapshotObjectStore by refactoring the Pimpl pattern, moving the destructor from the header to the source file to resolve incomplete type issues with std::unique_ptr. Enhanced build automation and CI stability by implementing a smart GOPROXY configuration in Shell scripts, enabling automatic detection of restricted-network conditions and selective proxy routing. These changes improved Go module download reliability, particularly in environments with limited network access, and streamlined the development workflow using C++ and Shell scripting expertise.
