Proficient with Terraform for provisioning, automating, and managing cloud and Kubernetes infrastructure at scale.
Solid understanding of systems engineering and networking fundamentals, including proxy-based architectures, workload identity and authentication, service-to-service communication, and TCP/IP networking concepts within cloud environments.
Experience with cloud-native infrastructure tooling and frameworks such as Crossplane, Terragrunt, cert-manager, Kubernetes Load Balancer Controllers, or similar technologies used to support scalable and secure platform operations.
Prior experience creating, maintaining, and troubleshooting Kubernetes manifests, Helm charts, and YAML-based configurations.
