System Administrator Tata Consultancy Services
I administered and maintained more than 300 Linux and Windows servers in an enterprise production environment, focusing on high availability and compliance.
I resolved an average of 12+ incidents and tickets daily through ServiceNow, troubleshooting connectivity issues, SSH outages, network adapter faults, security access changes, and storage alerts.
I also automated user administration and package management with Bash, provisioned virtual machines in VMware vCenter, performed OS upgrades, expanded storage with LVM, and supported security tooling and SIEM integrations.
