Contributed to the 86Box/86Box project by delivering targeted cross-platform enhancements and maintainability improvements over a two-month period. Focused on C and C++ development, the work included refactoring the VMManager display naming for better namespace hygiene and implementing FreeBSD-specific build configurations using CMake to ensure reliable compilation across platforms. Addressed Linux and Windows build blockers by resolving header conflicts and introduced safer IOCTL code paths with improved buffer management. Added timer functionality for floppy IOCTL on Linux, consolidating related code for maintainability. These efforts strengthened system programming reliability and set a foundation for future cross-platform development within the repository.
