Worked on the InsightSoftwareConsortium/ITK repository to improve code quality by refactoring a core macro related to object copying and moving. The effort involved renaming ITK_DISALLOW_COPY_AND_ASSIGN to ITK_DISALLOW_COPY_AND_MOVE, aligning the macro’s intent with modern C++ move semantics and preparing the codebase for future legacy removal. This change preserved existing behavior when legacy settings were enabled, ensuring backward compatibility while enhancing code clarity and maintainability. The work demonstrated disciplined application of C++ and code refactoring skills, with careful attention to macro hygiene and adherence to ITK coding standards, supporting long-term stability and easier future updates across the repository.
