Harish rawat

I am a dedicated Linux System Administrator with over 2.11 years of hands-on experience managing large-scale RHEL, CentOS, and Oracle Linux environments. I specialize in system lifecycle management, including installation, configuration, patching, and OS upgrades, and I have managed thousands of servers while maintaining secure, stable production systems.

I have implemented automation with Ansible and shell scripting, improved operational efficiency with cron jobs, and led migrations from RHEL 7 to RHEL 8/9. My day-to-day responsibilities include managing services such as Apache, NGINX, FTP, Samba, NFS, NTP, and rsyslog, configuring LVM, ACLs, and firewall rules, and resolving performance, boot, and disk issues with minimal downtime.

I collaborate with global teams through ticketing systems like ServiceNow and Jira, contribute to deployment and incident-response activities, and maintain thorough documentation. I am committed to reliability, security, continuous improvement, and am available to join immediately with flexibility for 24x7 environments.
