Hands-on Linux System Administrator with strong experience in DNS, monitoring, backup automation and virtualization, now expanding into DevOps practices. I design and maintain dnsmasq and BIND name services, run Nagios-based monitoring with actionable alerts, and build reliable backup workflows for support systems. I keep production services stable, quickly resolve storage or memory incidents, and document recovery steps so teams can restore service with confidence. Key accomplishments include building a Java/JSP support tracker on Tomcat with automated mysqldump backups and offsite transfer, creating Nagios checks that send HTML alerts and recovery notifications with duplicate suppression and escalation reminders, containerizing legacy support sites with Docker Compose, and deploying MRTG/Cacti graphs for network visibility. I am actively learning CI/CD, Terraform and Ansible to automate deployments and infrastructure
