Most clients don't hire me to simply manage servers, they bring me in when something critical needs attention.
A domain controller stops replicating. An RDS environment becomes unstable. Firewall rules break remote access. Backups fail silently. Virtual machines suffer performance issues. Infrastructure has been inherited with little or no documentation.
My role is to quickly identify the root cause, stabilize the environment, implement best practices, and leave behind clear documentation so the infrastructure is easier to support going forward.
