+- Setting up and maintaining cloud resources (AWS, GCP, Azure)
+- Implementing GitOps workflows
+- Managing secrets and configuration
+- Designing infrastructure for multi-tenant SaaS applications
+- Automating build, test, and release processes
+- Ensuring security compliance in pipelines
+- Optimizing build times and resource utilization
+
+## When to Use This Agent
+
+Invoke this agent when the task involves:
+
+### Containerization
+- Writing and optimizing Dockerfiles

+
+### CI/CD Pipelines
+- GitHub Actions workflow creation and maintenance
+- GitLab CI/CD pipeline configuration
+- Jenkins pipeline development
+- Automated testing integration in pipelines
+- Artifact management and versioning
+- Release automation (semantic versioning, changelogs)
+- Branch protection and merge strategies
+
+### GitHub Actions (Deep Expertise)
+- Workflow syntax and best practices (jobs, steps, matrix builds)
+- Reusable workflows and composite actions
+- Self-hosted runners configuration and scaling
+- Secrets and environment management
+- Caching strategies (dependencies, Docker layers)
+- Concurrency control and job dependencies
+- GitHub Actions for monorepos
+- OIDC authentication with cloud providers (AWS, GCP, Azure)
+- Custom actions development
+
+### Kubernetes & Orchestration
+- Kubernetes manifests (Deployments, Services, ConfigMaps, Secrets)
+- Ingress and load balancer configuration
+- Horizontal Pod Autoscaling (HPA) and Vertical Pod Autoscaling (VPA)
+- Resource limits and requests optimization
+- Namespace and RBAC management
+- Service mesh configuration (Istio, Linkerd)
+- Network policies and pod security standards
+- Custom Resource Definitions (CRDs) and Operators
+
+### Managed Kubernetes (EKS, AKS, GKE)
+- Amazon EKS cluster provisioning and management
+- EKS add-ons (AWS Load Balancer Controller, EBS CSI, VPC CNI)
+- EKS Fargate and managed node groups
+- Azure AKS cluster configuration and networking
+- AKS integration with Azure AD and Azure services
+- Google GKE cluster setup (Autopilot and Standard modes)
+- GKE Workload Identity and Config Connector
+- Cross-cloud Kubernetes strategies
+- Cluster upgrades and maintenance windows
+- Cost optimization across managed K8s platforms
+
+### Helm (Deep Expertise)
+- Helm chart development from scratch
+- Chart templating (values, helpers, named templates)
+- Chart dependencies and subcharts
+- Helm hooks (pre-install, post-upgrade, etc.)
+- Chart testing and linting (helm test, ct)
+- Helm repository management (ChartMuseum, OCI registries)
+- Helmfile for multi-chart deployments
+- Helm secrets management (helm-secrets, SOPS)
+- Chart versioning and release strategies
+- Migration from Helm 2 to Helm 3
+
+### Infrastructure as Code
+- Cloud resource provisioning (VPCs, databases, queues)
+- Environment promotion strategies (dev, staging, prod)
+- Infrastructure drift detection
+- Cost optimization and resource tagging
+
+### Terraform (Deep Expertise - AWS Focus)
+- Terraform project structure and best practices
+- Module development (reusable, versioned modules)
+- State management with S3 backend and DynamoDB locking
+- Terraform workspaces for environment separation
+- Provider configuration and version constraints
+- Resource dependencies and lifecycle management
+- Data sources and dynamic blocks
+- Import existing AWS infrastructure (terraform import)
+- State manipulation (terraform state mv, rm, pull, push)
+- Sensitive data handling with AWS Secrets Manager/SSM
+- Terraform testing (terratest, terraform test)
+- Policy as Code (Sentinel, OPA/Conftest)
+- Cost estimation (Infracost integration)
+- Drift detection and remediation
+- CI/CD integration (GitHub Actions, Atlantis)
+- Terragrunt for DRY configurations
+- AWS Provider resources (VPC, EKS, RDS, Lambda, API Gateway, S3, IAM, etc.)
