Back to original languageAbout Jonathan
Do you have OpenShift or Kubernetes clusters that need to remain stable, performant, and secure?
I help youavoid production incidents**, **quickly resolve complex issuesthat your teams can't handle, andindustrialize your deploymentsto make them repeatable and reliable.
What I bring you concretely:
- N3 Troubleshooting : I diagnose and resolve your critical incidents (Control plane, networking, storage, operators) – with Red Hat Support escalation if needed
- Risk-free Upgrades : I manage your OpenShift version upgrades, validate operator compatibilities, and security patches
- Optimized Performance : capacity planning, quotas/limits, scheduling – so your cluster never saturates
- Security & Compliance : RBAC, SCC, secrets, Network Policies – your environments pass audits
- IaC Automation : industrialized deployments via Ansible, GitOps, ArgoCD – no more risky manual deployments
My difference:
I amRed Hat Certified Engineer in OpenShift– I know OpenShift in depth, not just generic Kubernetes. I speak technically with your developers AND with Red Hat Support. I am an independent freelancer, so reactive and aligned with your costs, not on selling licenses.
Are your clusters critical to your business? I keep them stable, secure, and performant – so you can focus on your business.
