Worked on stabilizing C and C++ integration within the facebookincubator/cinder repository, focusing on resolving cross-language compatibility issues. Addressed a critical bug by wrapping PyTraceMalloc_ functions with extern "C" to ensure proper linkage when interfacing with C++ compilers, following Python.h and Python C-API conventions. This approach reduced the risk of C++-specific linkage errors and improved long-term maintainability for the codebase. Utilized skills in API design, C programming, and C++ programming to validate the integration and prevent future build issues, contributing to a more robust and reliable development environment for projects relying on mixed-language components.
