I’ve supported application onboarding, traffic segmentation, and scalable Layer 2 and Layer 3 connectivity using Cisco Nexus and Arista platforms.On the WAN and cloud side, I’ve worked with Cisco Viptela SD-WAN, including secure internet breakout and Zscaler integrations to improve SaaS performance. I also support hybrid cloud networking across AWS and Azure, working with VPCs, routing, load balancing, and security controls.Automation is a regular part of my work.
