At Techs Duniya, I administered and monitored enterprise RHEL and Ubuntu staging servers, maintaining 99.8% continuous service uptime while handling root-cause analysis and incident triage.
I provisioned LVM storage and expanded ext4 and XFS partitions. I also configured persistent mounts, scheduled snapshots, and automated offsite backups.
I automated maintenance workflows, user onboarding, and log rotation with Bash scripts, Cron, and systemd timers, reducing manual administrative ticket volume by 40%.
I hardened Linux hosts with SELinux policies and firewall rules, managed software patching and kernel upgrades, and troubleshot system bottlenecks. I also configured Nginx and Apache with reverse proxy rules and SSL/TLS termination.
