• Demonstrated ability to independently turn ambiguous business objectives into technical designs, phased delivery plans, and measurable outcomes across multiple services or teams.

• Deep experience with at least one major cloud provider-AWS, Azure, GCP, or OCI-and demonstrated application of billing, utilization, allocation, and capacity data to cloud optimization decisions.

• Proficiency designing and operating cloud-native services with CI/CD, automated testing, and infrastructure as code using tools such as GitHub Actions, Jenkins, Terraform, or equivalent technologies.

• Experience with microservices, containers, and orchestration platforms such as Docker, Kubernetes, EKS, or OKE.
