This entire infrastructure — Kubernetes cluster, GitOps pipeline, monitoring stack, and demo app — is running live on a single ARM server provisioned for free on Oracle Cloud.
A complete DevOps ecosystem running on a single ARM instance
Two ways to look at the same running cluster: raw data straight from the Kubernetes API, or the Grafana dashboards it feeds.
Virtual creatures living as Kubernetes pods. Feed them or they die — and every action becomes a Prometheus metric.
I'm an independent DevOps & Platform Engineer with 12+ years of experience. This site isn't a slide deck — it's a production cluster you can click through right now. That's the same rigor I bring to your platform.
The cluster you're browsing is not a managed service. I architected and provisioned every layer of it myself on Oracle Cloud: VCN and subnet design, route tables, internet and NAT gateways, security lists and firewall rules, compute instance sizing (ARM Ampere A1), block and boot volumes, DNS records and TLS termination. Kubernetes only came afterwards — on top of a network I had drawn first. None of it is clicked in a console: the network and the instance are declared in Terraform, everything inside the machine and the cluster in Ansible. Both are public, and rebuild the whole platform from zero in under an hour.
Multi-cloud and bare-metal virtualization are my daily work at EXFO, across 11 Kubernetes clusters — Oracle Cloud is simply where I pay for it myself.
Design, migration, and hardening of K8s clusters (EKS, AKS, OpenStack, K3s). Internal Developer Platforms and Golden Paths that let your teams ship without opening a ticket.
ArgoCD App-of-Apps, GitLab CI, Gitea Actions, Terraform and Crossplane. On my last assignment: release cycles cut by 40% and deployments that stopped being an event.
Prometheus, Grafana, Loki, meaningful SLOs and alerts that actually wake the right person. From blind infrastructure to a 99.9% SLA you can prove.
Trivy/SBOM scanning built into the pipeline, network policies, secrets management — and a cloud bill audit, because the best-architected platform is also the one you can afford.

Time & materials or fixed price · short audits as well as long-term assignments · first call always free.
Every layer is declared as code, and the code is public. If this server disappeared tonight, one terraform apply and one ansible-playbook would bring it all back in under an hour — network, cluster, GitOps, observability, applications and data.
stops where the Oracle API ends
VCN, subnet, internet gateway, route table, security list, the ARM instance, and a reserved public IP. Terraform is used for what it does best: cloud resources that have a state, where drift must be detected and a plan reviewed before anything changes.
everything inside the machine and the cluster
Packages, firewall, K3s, Helm releases, manifests, images, backup timer. Ansible is used where Terraform would only have local-exec: it is idempotent, replays on a live cluster to correct drift, and turns Helm values into versioned files instead of leaving them buried in a release's state.
The full recovery procedure — including the three traps that cost me hours: the K3s cloud-provider flags that silently taint the node, Linkerd breaking ArgoCD's internal gRPC, and Oracle's Ubuntu image dropping ports 80 and 443 whatever the security list says.
