Wahab A.

I build and troubleshoot Kubernetes platforms, automate deployments with Argo CD and Terraform, and set up Prometheus and Grafana monitoring. CKA-certified, with experience across 9 clusters and 110 applications. I help SaaS and infrastructure teams make releases repeatable, understand production issues, and keep Kubernetes environments maintainable. HOW I CAN HELP • Kubernetes & K3s: Cluster setup, workload troubleshooting, Helm deployments, NGINX Ingress, TLS certificates, secrets, storage, and migrations across AWS/EKS, Hetzner, Linode, and bare metal. • GitOps with Argo CD & Terraform: Version-controlled infrastructure, Kubernetes manifests and Helm charts, automated deployments, and CI/CD integration with GitLab, Jenkins, or AWS CodePipeline. • Monitoring & observability: Prometheus, Grafana, kube-prometheus-stack, Loki, OpenTelemetry, and CloudWatch. Centralized dashboards, alerting, Blackbox Exporter, and checks for uptime, latency, HTTP status, and TLS expiry. • Infrastructure automation: Linux and Ansible operations, cert-manager, External Secrets, DNS automation, backups, and private-network access. RELEVANT PROJECTS • Multi-cloud GitOps platform: Terraform-managed infrastructure and Argo CD deployments across 9 Kubernetes clusters hosting approximately 110 applications. • Centralized monitoring: 10 Kubernetes clusters, multiple servers, and 250+ production and test sites, with automated discovery and alerting. • AWS-to-Hetzner migration: Replatformed a production application on K3s with approximately 80% infrastructure cost savings and near-zero downtime. You can review these case studies in my portfolio. My background also includes operating 800+ servers and reducing AWS spend from $59.8K to $24K per month. I hold the Certified Kubernetes Administrator (CKA) certification. Share your Kubernetes environment, deployment workflow, or monitoring gaps in an Upwork message. We can start with a focused audit or troubleshoot a specific issue, then scope the implementation around your priorities.
