Rizwan Sabir

I am a Network Engineer with over 7 years of hands-on experience in implementing, troubleshooting, and maintaining robust network infrastructures for service providers. My expertise lies in managing large-scale IP/MPLS networks, ensuring high availability, scalability, and performance. I have a proven track record of configuring and troubleshooting Cisco and Juniper devices, which has enabled me to deliver reliable connectivity solutions that meet both customer and business demands.

Currently, I work at GTT Communications, where I am responsible for monitoring core network and customer services, performing diagnostics on network faults, and managing incident escalations. My role requires me to coordinate with local field operations and vendors to diagnose and resolve issues across the Pan-European and Pan-American networks. Previously, I served as a Service Delivery and Assurance Engineer at Reliance Jio Infocomm Ltd., where I provided end-to-end enterprise service connectivity and technical support to field engineers and customers.
