Modassar Rana expanded cross-architecture build support for the opendatahub-io/model-registry repository, focusing on enabling s390x architecture compatibility. He updated the Makefile and install_protoc.sh scripts, introducing logic to detect and build on s390x systems, which addressed platform-specific build failures and streamlined the CI/CD process. His work involved enhancing build systems and shell scripting to ensure that future integrations would require minimal adjustments for new architectures. By aligning the build tooling and workflow details, Modassar improved the maintainability and scalability of the project’s build infrastructure, demonstrating depth in build automation and cross-platform engineering using Makefile and shell scripting.
