Experience
Senior Network Engineer
Wintrust Financial Corporation
Feb 2025 — Present
I am responsible for designing and implementing scalable and resilient enterprise network architectures across on-prem and Azure environments. I led the deployment of spine-leaf data center networks using Arista EOS with VXLAN EVPN, enabling high-performance connectivity. I developed zero-trust security architectures leveraging Azure NSGs and Palo Alto firewalls, while also implementing hybrid connectivity using ExpressRoute and VPN solutions. My role involves optimizing wireless infrastructure using Cisco AireOS and Meraki, automating Azure networking components through Terraform, and enhancing network visibility using telemetry tools. I also engineered high-availability solutions, including HSRP/VRRP redundancy, DNS-based traffic steering with F5 GTM, and DWDM-based backbone connectivity for high-speed data transfer.
