Worked on the OpenMontage repository to enhance the build system by standardizing Python usage to Python 3 throughout the Makefile. This update ensured that all build automation scripts invoked python3 explicitly, addressing compatibility issues and reducing environment-related build failures. The approach focused on future-proofing the pipeline by aligning the repository with modern Python workflows, which is essential as Python 2 reaches end-of-life. Leveraged Makefile scripting and Python development skills to deliver this targeted improvement. No additional features or bug fixes were reported during this period, reflecting a focused effort on stabilizing and maintaining the build infrastructure for ongoing development.
