Worked on expanding the eco-gotests repository to support the S390x architecture, enabling deployments on IBM zSystems. The contribution focused on cross-platform development by introducing new image and kernel definitions, along with constants for s390x DTK images and kernels, ensuring accurate resource identification and deployment processes. Leveraging Go and system architecture expertise, the work laid the groundwork for multi-architecture readiness and future architecture-specific testing within eco-gotests. The implementation was delivered as a single, targeted feature, reflecting a methodical approach to extending platform compatibility without introducing regressions or bugs, and strengthening the foundation for robust cross-architecture validation workflows.
