  • Experience maintaining Windows Server environments, including hardening, patching, upgrades, and disk management.
  • Experience administering Linux servers, including patching and software maintenance.
  • Experience with IAVA patching and reporting.

  • Hands-on experience with AWS services such as EC2, Lambda, CloudFormation, and IAM.
  • Experience with automation and scripting tools including Ansible, Terraform, PowerShell, Bash, and Python.
