• Integrate static and dynamic code analysis tools (e.g., SonarQube) into the CI/CD process.
• Manage secure access to AWS services using IAM roles, least privilege principles, and container-based identity (e.g., workload identity).
• Create and manage Helm charts for Kubernetes deployments across multiple environments.
