Amalarajan S

I’m an Infrastructure engineer with 8+ years of experience administering hybrid Windows and UNIX/Linux environments across on-premises, AWS, and Azure platforms. I bring hands-on expertise in virtualization (VMware vCenter, ESXi, Hyper-V, Citrix), Windows Server management, and identity and access administration through on-prem AD and Microsoft Entra ID.

In my current role as SYSTEMS ADMINISTRATOR / INFRASTRUCTURE ENGINEER (HYBRID CLOUD) at FIS GLOBAL, I’m responsible for the administration, monitoring, and support of a hybrid Windows and Linux server environment spanning on-premises and AWS. I manage virtualization, identity and access, patching, backups, and end-to-end system health to ensure high availability, security, and operational efficiency—covering Hyper-V infrastructure, AWS EC2 workloads, Microsoft SCCM (MECM), SolarWinds monitoring, and Commvault backup operations.

Previously, I worked as a SENIOR LINUX ADMIN at HCL TECH, supporting a US client Linux team with system administration, installation, upgrades, patches, migration, security, and disaster recovery. Earlier, as a LINUX SYSTEM ADMINISTRATOR at ORAMATE SOLUTION ENDS, I handled VMware ESXi-based Red Hat Linux environments, LVM, NFS/CIFS, Ansible automation, Git-based code updating, and Bash/Python scripting—while improving processes to reduce downtime and strengthen security patching and vulnerability remediation.
