Brendon Ravello

Tier 3 Linux administrator · author of linuxadmin.work

Profile

Brendon Ravello is a Linux system administrator with five years of experience running production RHEL, AlmaLinux, CentOS, and Ubuntu Server environments supporting anti-malware research, high-traffic websites, and ecommerce services, where uptime and the integrity of live data are the measures that matter.

Much of his work removes manual effort from operations. He writes Bash and Python scripts and Ansible playbooks so that recurring work — deployment, weekly patching, and configuration rollout — runs the same way every time instead of depending on an operator's memory. The aim is repeatability: fewer hand steps, fewer surprises, and a smaller surface for mistakes.

Brendon is a Tier 3 escalation point. He takes L2/L3 incidents, works them to resolution within strict SLA targets, and keeps high-availability Apache and NGINX web services serving behind iptables/firewalld. Certificate lifecycle work, from configuration through renewal, is part of that service ownership.

He works deliberately on the defensive side of operations: proactive monitoring, server hardening, and dependable uptime. In environments that handle live malware samples, that discipline extends to isolated static-analysis systems as well as the web estate, with patch windows coordinated to protect research availability.

Across distributed, multi-site infrastructure, he favors clear ownership and dependable systems over heroics. He holds CompTIA Linux+ and CompTIA A+ certifications and is based in Roswell, Georgia.
