During May 2025, Tchaikov worked on modernizing the build system for the Mooncake repository, focusing on robust dependency management and maintainability. By leveraging CMake and C++ skills, Tchaikov implemented find_package() for external libraries such as glog, gflags, and jsoncpp, ensuring dependencies are properly detected and linked using CMake targets. This approach improved configuration-time error reporting and compatibility with custom installation prefixes, reducing future maintenance risks. Additionally, Tchaikov contributed to the fmt repository by correcting comment typos, enhancing code clarity. The work emphasized best practices in build systems, dependency management, and code documentation, laying groundwork for smoother future upgrades.
