Cristi VLAD

DevOps / Kubernetes Engineer – Rancher | RKE1/RKE2 | Terraform | Docker • Designed, deployed, and operated 70+ on-premises Rancher RKE1 Kubernetes clusters, supporting diverse development workloads with high reliability and scalability. • Built robust, reusable Terraform modules to automate the deployment of key components into Kubernetes, including:   - Elastic Cloud on Kubernetes (ECK)   - Istio Service Mesh   - NGINX Ingress Controller   - vSphere integrations and CSI drivers (vSphere, SMB, Isilon)   - Kubeflow, SonarQube, ReportPortal, and Vault • Automated full lifecycle management of Rancher management clusters and Rancher downstream clusters using Terraform and GitOps workflows. • Used Azure DevOps for Git source control and CI/CD, creating pipelines to deploy infrastructure using parameterized Terraform templates. • Led the migration from Azure DevOps Library to HashiCorp Vault for secrets management, integrating Vault with Terraform via Vault Secrets Operator for secure, dynamic secret handling. • Managed Docker image workflows through Terraform-based Artifactory configuration, covering repository setup and artifact versioning. • Orchestrated the complete migration from RKE1 to RKE2 across 70+ clusters using in-house developed Terraform modules. Scope included:   - Node provisioning, firewall rule configuration   - Infrastructure automation via Terraform   - CI/CD pipeline development for migration   - Re-deployment of third-party integrations post-migration • Deep hands-on expertise with Kubernetes, Docker, Rancher (RKE1/RKE2), and Terraform, with a strong focus on scalability, automation, and platform resilience.

Creating the platform for developers Multiple PKS Kubernetes clusters for multiple development teams Using ArgoCD as container orchestrator Using Helm and Kustomize as package/repo manager Using Jenkins integrated with bitbucket for app build docker image build and push into Artifactory Using Helm and Kustomize to deploy apps from ArgoCD into kubernetes clusters Using Vault for secrets store Using Splunk for monitoring Using Prometheus with grafana for metrics (federation) Using Istio for service mesh (mTLS between apps) Using Velero-restic for backup and restore Using cert-manager for certifcates and vault PKI

Write helm charts for Kafka, ETCD & Zookeeper on various development Kubernetes evironments Implement testing framework using python nose testing - write various scenarios for helm charts testing (upgrade, downgrade, upscale, downscale, delete pod, write into ETCD without permissions) Maintain Artifactory repositories for dev, uat & prod for Helm Charts and Docker images used by helm charts Building complete CI/CD workflow for Kafka, Zookeeper & ETCD helm charts (build charts, upload them to Artifactory, execute nose tests and publish into production repo -- all using Jenkins jobs) Using Jira for ticketing & confluence for documentation Working Agile
