  • Hands-on experience with enterprise container orchestration platforms, specifically OpenShift or Kubernetes.
  • Experience writing automation and configuration scripts (e.g., Bash, Python) to streamline cluster maintenance.
• Troubleshooting Focus: Proven ability to diagnose and resolve complex hardware, network, and OS-level issues.
