Sowmya Gadde

I’m a Senior Network Engineer with 6 years of experience designing, architecting, and operating enterprise-scale LAN, WAN, data center, SD-WAN, and cloud networking environments. I focus on routing and switching depth (BGP, OSPF, VLANs, STP, HSRP/VRRP) and delivering high-availability architectures with Cisco Nexus and Arista data center platforms.

In my current role, I architected and operated a highly available Cisco Nexus–based data center using redundant core and aggregation layers, implementing L2/L3 designs with VLANs, HSRP, OSPF, and BGP for nonstop core production connectivity. I also engineer end-to-end QoS for VoIP readiness, build resilient WAN designs with Prisma SD-WAN, and deliver Zero Trust traffic flows by integrating Zscaler (ZIA/ZPA) with Prisma SD-WAN edges and enforcement points. On the security side, I deploy Palo Alto firewalls and integrate Fortinet for defense-in-depth, while implementing Cloudflare WAF for OWASP protection and layered application isolation.

Previously at Wells Fargo and Accenture, I built modern data center designs (including Arista leaf–spine with BGP and MLAG), implemented Cisco SD-WAN (Viptela), and enforced identity-driven access using Cisco ISE and Aruba ClearPass (802.1X, posture, dynamic VLAN assignment). I’m known for owning production networks, performing architect-level troubleshooting (routing loops, asymmetric flows, SD-WAN instability, firewall conflicts), and centralizing telemetry and logs into Splunk to drive rapid restoration, root-cause elimination, and ongoing performance and compliance alignment.
