  • Conduct Well-Architected Framework reviews and convert findings into actionable modernization backlogs.
  • Define and implement Infrastructure-as-Code (IaC) standards using Terraform or similar technologies.
  • Establish CI/CD standards to support repeatable and automated deployments.
  • Work closely with Security teams to embed security, vulnerability management, and compliance controls into cloud modernization initiatives.
  • Provide architectural guidance across Cloud, WAF, PKI, IAM, and infrastructure security.
  • Identify opportunities for automation and self-service to reduce manual operational effort.
  • Ensure appropriate resource tagging and governance across cloud environments.
  • Collaborate with technical and business stakeholders and provide regular updates on modernization progress.
