  • Understand how cloud IAM models and networking primitives (VPC peering,: private connectivity, service mesh) differ across providers

  • Write production code in at least one general-purpose programming language (e.g., Python, Go, or Rust)

  • Work confidently with Kubernetes and Infrastructure as Code (e.g., Terraform, Pulumi)
