What I'm looking for

I’m seeking a senior network engineering or technical leadership role in SD-WAN (Cisco Viptela), MPLS VRFs, and secure, scalable infrastructure—leading deployments, automation, incident resolution, and stakeholder-driven modernization.

I’m a results-driven Network & Cloud Technical Lead with 11 years of experience delivering CORE COMPETENCIES in large-scale infrastructure transformations across global enterprise environments. I lead SD-WAN deployments, cloud migrations on AWS/Azure, BGP/routing implementations, and security governance for enterprise networking supporting 40,000 devices.

In my current Technical Lead - Network Infrastructure role at Citi, I lead implementation of complex network changes on 40,000 devices with 99.9% uptime and complete change-management compliance. I accelerated modernization with Cisco Viptela SD-WAN deployment—handling OS upgrades, VXLAN/MPLS-aware routing changes, DNS updates, and legacy decommissioning—while resolving high-severity incidents within SLA through Root Cause Analysis.

I also build automation and governance that scale: I created Python and Ansible scripts for configuration management and API integrations, reducing manual effort and error rates by 30%, and I led CyberArk privileged access migration to enforce zero-trust access governance and IAM policy compliance. Previously, I led end-to-end projects and supported cloud and networking delivery across AWS VPC/EC2/S3/IAM/EKS and Azure VNet/ExpressRoute, while improving reliability and monitoring coverage using tools like ServiceNow, Nmap, Tenable, and Spectrum.
