Sr. Network Engineer

Responsibilities:

• Migrating the restaurant network from Cisco 1800 to Juniper SRX 100, SRX 240 routers. This was done to provide more security to the network and to provide redundant link to the Datacenter in case of the failure of T1 Link. Each restaurant have access to internet without going through the data center which eliminates possibility of the security threats. Worked with the restaurant technician to setup the network, configure SRX devices and trouble shoot the issues in the network. Making sure the network is setup as per the network design document.
• Resolved the technical issues assigned to me reported by the restaurants. Connectivity issues from the restaurant network to Wireless Aruba controller, Ziosk and DASH server.
• Network was setup for the new restaurants as per the network design. Gained experience in configuring SSO (Stateful Switchover), IPsec Tunnel on core Cisco 12K router to provide redundancy and security in the Data Center Network. Built a large-scale HSRP solution to improve the uptime of network for all restaurants, in the event a core router became unreachable.
• Remote implementation of Citrix NetScaler load balancing products.
