What I'm looking for

I'm looking to build and modernize scalable, resilient enterprise data center and hybrid cloud networks, solving complex infrastructure challenges and improving reliability, performance, and operational efficiency.

At Cisco Systems, I designed and delivered large-scale enterprise data center and core network infrastructure for mission-critical environments, improving stability, scalability, and availability.

I've built Cisco Nexus, UCS, and ACI spine-leaf platforms; optimized VXLAN, EVPN, SDN, OSPF, BGP, MPLS, and AWS hybrid connectivity; and supported VMware vSphere clusters with HA, DRS, and performance tuning. I also developed Python automation scripts to improve validation, troubleshooting, and operational efficiency.

Across Diversant/Vircon, Wipro Tech, Del Oro, and Questivity, I've supported Cisco data center, SAN, LAN/WAN, VPN, routing, switching, firewall, and virtualization environments. I bring 14+ years of hands-on infrastructure troubleshooting, root cause analysis, and modernization work.
