My responsibilities remain the same as in Ventus. In addition, I have enabled the cloud platform to leverage Nvidia GPUs (A100, H100, H200, L40S) both for standard virtual machines and as GPU nodes in Kubernetes. I also deliver client-specific, pre-configured GPU environments powered by Kubeflow, providing efficient training and serving of AI models through Infrastructure as Code.
