What I'm looking for

I’m looking for a hands-on infrastructure role where I can own RHEL/Windows administration, improve reliability and security, and support SLA-driven operations—while expanding my Kubernetes and enterprise storage expertise in a collaborative team.

I’m an RHCSA-certified system administrator with hands-on experience administering Linux (RHEL) and Windows Server in enterprise, high-availability environments. I focus on dependable operations—installing, configuring, and troubleshooting OS, applications, and services for performance, stability, and SLA compliance.

In my current role at the NRSC–ISRO computer maintenance environment, I manage RHEL user administration, monitoring, performance tuning, and enterprise storage using LVM, RAID, NFS, iSCSI, and multipathing. I also support Windows Server administration (Active Directory and Group Policy), administer Kubernetes clusters (kubeadm) for scaling and deployments, and implement backup/recovery with Veeam alongside NetApp storage.
