*** Build and maintain IaC modules and standards (e.g., Terraform, Cloud Formation, CDK) for repeatable, auditable infrastructure delivery.
* Develop, standardize, and optimize CI/CD pipelines to enable safe, automated deployments (e.g., Git Hub Actions, Git Lab CI, Jenkins, AWS Code Pipeline).
* Promote Dev Ops practices: version-controlled infrastructure, automated testing, immutable deployments, and progressive delivery patterns.
* Establish environment consistency across dev/test/stage/prod and ensure infrastructure drift detection and remediation.
** BCP/DR, RTO/RPO Definition & Testing
