Work Experience

Primacy SI – Network Architect

Working on Cloud, Security and Infrastructure Technologies (October 2021-Present)

Design and deployment of networking in Azure and AWS clouds for SDWAN using Aviatrix connecting remote sites to Multi-cloud setup. High level design:

oIPSEC tunnel from Aviatrix Transit Gateway to Silver peak

oThe MPLS provider which connects all remote sites had connection to AWS direct connect which was then connected to Transit gateway

oTransit gateway had multiple routing tables and hence route propagation had to be used for exchanging routes from routing table attached from direct connect to other routing tables

oRoutes from Transit gateway were then advertised to Aviatrix which was the transit for all traffic from cloud resources to site connectivity

Deployment of Express route with Virtual Hub and Azure premium firewall providing secure access to cloud services from onprem

Implemented multi VRF VXLAN on Cisco Nexus and Catalyst Switches with Border leaf connected to Palo Alto firewall providing security for both east-west and north-south traffic

Deployed Cisco SDA solution with Cisco Firewall as Fusion device, Catalyst 9500 as Core and 9300/9400 devices as part of SDA
