What I'm looking for

I'm looking to lead and improve reliable, scalable enterprise network infrastructure, including global WAN, data center, routing, switching, security, and modernization initiatives.

I've built and supported enterprise network infrastructure for Sedgwick Claims, Enfusion, Enlivant, and Suzlon Wind Energy, covering global WAN, branch, data center, and secure connectivity environments.

At Sedgwick Claims, I maintain a global MPLS backbone using BGP traffic engineering and VRFs, lead architecture for greenfield deployments and modernization, and administer Palo Alto, Cisco ASA, F5 BIG-IP LTM, NAT, and IPsec VPN services. Previously at Enfusion, I designed scalable spine-and-leaf data center connectivity using Arista, Cisco Nexus, VXLAN EVPN, BGP, OSPF, IS-IS, and SR-MPLS for global financial services applications.

I bring more than 12 years of hands-on experience troubleshooting complex routing, switching, and connectivity issues, improving visibility through monitoring and observability, and creating standards, topology diagrams, and documentation that support reliable long-term operations.
