Worked on modularizing and stabilizing C++ codebases across ggml-org/llama.cpp, Mintplex-Labs/whisper.cpp, and FreeCAD/FreeCAD. Exposed ggml-cpp.h as a public header via CMake configuration, enabling external integration and improving API accessibility for downstream projects. Enhanced runtime robustness by implementing Ctrl+C handling in command line audio streaming, ensuring graceful exits and preventing unresponsiveness. In FreeCAD/FreeCAD, addressed a critical issue in the Fanuc post-processor by removing a trailing percent from G-code output, preventing controller hangs during drip feeding. Leveraged C++, CMake, and Python, with a focus on build system configuration, error handling, G-code generation, and unit testing.
