WORK EXPERIENCE:

Nvidia Network Support Engineer June 2017- Present Planning and implementation activities for building LAN/WAN. Assist in troubleshooting and verifying newly constructed Network Infrastructure. Perform client side network validation tests. Technologies include OSPF, VLANs, LACP, ACLs, NAT, VRRP, RSTP, Cisco Catalyst 4550E, 6500, Juniper Ex 4200, Arista switches. Edgewater Networks Technical Support Engineer July 2016 - Aug 2016 Provided customer support and worked with development and TAC teams as needed to troubleshoot and resolve issues. Technologies include Routing and Switching, DHCP, SIP/H.323 protocols. IPsec and SSL VPNs related issues, managing and configuring stateful firewalls. Worked in Linux virtual environment VSphere 5.5/6. Tools used tcpdump, Wireshark, iptables.

Suggestmychoice.com Assistant System Engineer July 2013 - April 2014 Assisted in managing and monitoring running application on AWS EC2. Diagnosing elastic load balancing, security groups (TCP/IP, HTTP, SSL/TLS). Maintaining private networks and configuring VPN, IPSec, ISAKMP and secure network systems using ASA firewall. Predicting network traffic load flow and report generation. RELEVANT PROJECT WORK:

Master Project: Video Streaming Application Aware Packet Routing in SDN. Video on Demand requires routing path with less packet loss whereas Live Streaming requires less packet delay routing path. Developed python based controller application to calculate metric with least cost routing path for each of TCP-based Video-on-Demand and UDP-based Live Streaming. Demonstrated on Mininet, Iperf, Wireshark. BGP, OSPF and EIGRP implementation: Simulated complex BGP routed network infrastructure that include Route-maps, AS-Path, local preference, Inter VRF routing across multiple ISP’s. Configured OSPF and EIGRP with multiple area types. Enabled me to interpret and resolve complex route tables, routes redistribution. Multiple routers and switches configuration and troubleshooting through automation: Created a SSH connection to the multiple networking devices and push configuration dynamically, automate repetitive tests and handling exceptions in Cisco Juniper network devices upon failure. Tools - Netmiko, JSON, traceroute.
