At Green Dot Corporation, I architected the Azure Virtual WAN backbone from the ground up and oversee network architecture across 133 Azure subscriptions. I also consolidated AWS networking into a centralized Transit Gateway spanning 150+ VPCs.
For Project Wolfsburg, I was the sole network engineering owner for the Fiserv/CBS to Temenos T24 migration, designing the Azure network, VPN, and NAT framework before the ExpressRoute cutover. The work spanned 25+ change windows with zero outages.
I built a Python and Panorama API pipeline that cut firewall change implementation from 4+ hours to under 45 minutes, and wrote nops, a Python library for parallel operations across 180+ devices. I also led migrations across live payment infrastructure with zero disruptions and supported three consecutive PCI penetration tests with zero network-layer findings.
