In December 2024, Josh Freeman refactored the build system for the XRPLF/rippled repository, focusing on modularizing the libxrpl library. Using C++ and CMake, he introduced new CMake functions to enforce module-levelization, which reorganized the internal structure into five distinct levels. This approach improved dependency management and header isolation, reducing cross-module coupling and laying the foundation for incremental builds. By enhancing the build system’s reliability and maintainability, Josh enabled safer module integration and streamlined future development. His work demonstrated depth in build system design, code refactoring, and library architecture, addressing long-term scalability and maintainability for the project.
