Worked on the redhat-appstudio-qe/infra-deployments repository to enhance CI/CD infrastructure for the VLLM pipeline by enabling support for newer AWS instance types, specifically arm64 (m7g+) and large-disk amd64. Focused on updating the host-config.yaml configuration to accommodate these changes, which improved build concurrency, resource availability, and scalability for VLLM testing and builds. Leveraged skills in AWS, cloud infrastructure, and configuration management, with all changes implemented in YAML. The work centered on performance optimization and reliable configuration updates, resulting in faster build and test cycles without introducing major bugs, and provided clear traceability for future infrastructure improvements.
