I'm a Linux Systems Administrator with enterprise experience at Atos | Syntel as an Associate Consultant, where I served as a first-level responder for infrastructure incidents — monitoring RHEL and Ubuntu servers for CPU, memory, disk, and network health, and ensuring SLA compliance. I have hands-on experience with ServiceNow ITSM, incident triage, root-cause analysis, SOP documentation, Bash automation, and vulnerability scanning using Nessus & Nmap. Currently deepening expertise in cybersecurity (CompTIA Security+ in progress) and cloud operations (AWS, AZ-900 certified). Ready to contribute immediately.
