Experience:

Cisco Lab Administrator at Universit of Bridgeport, CT - ID: #997279 (Feb'16 - May 17)

oAssisting professor in building topologies and assigning simple configuration tasks to the students

oWorked with HP Proliant DL360 G6 using operating system CentOS 7 where all the files are uploaded to the server and check for verification

oWorked with Network Engineers and installed Cisco ASA Firewalls

oManaged Network performance, providing daily operational support and system administration for core network infrastructure

o Worked on networks with WAN protocols such as MPLS, HDLC, ATM, PPP and Frame Relay

o Switching tasks include VTP, ISL/ 802.1q, VLAN, Ether Channel, LACP, PAGP, STP and RSTP

o Remote troubleshooting and fault finding if issues occurred upon initial installation

oEstablished Windows server 2012 and had connected to network for the remote access

oCreated user accounts and giving permissions to the accounts

oContinually monitor the networks of the buildings we manage to ensure the network is stable and the network equipment is functioning properly

oTroubleshoot and diagnosis of network error and failure, and upgrade the devices according to the requirement change

Programmer Analyst Trainee at Cognizant Technolgy Solutions, Coimbatore, India - ID: #491857 (Jun' 14 -May 15)

oAs a part of the controller and access points testing team used to conduct testing on level 2 authentication (security and encryption) of the device, connectivity to access points and creating ESSID

oTested the client association manager by connecting hundreds of client devices to the access point and making sure they can connect, disconnect, send and receive traffic

oTested the TCP/IP stack and measure the access point ability to handle the web traffic

oQuality of service is tested on the access point by generating different types of traffic with different settings. This makes sure the level of performance for each device and each type of traffic with your access points

oTested the client session manager on the access point to check the roaming of clients between WLAN cells

oTested the authentication and encryption mechanisms supported on the access points and ensure traffic is encrypted properly in all use cases

oLogged the defects in Mantis - a bug tracking tool by just giving ID to the bug that has been found.

oWriting test cases to determine whether controllers are satisfying the requirement by using Testlink

Training: Zoom Technologies, Hyderabad, India (Nov' 13 - May 14)

oConfigured Routers and Switches based on CCNA R&S Labs to create LAN/WAN Design

oMonitored Cisco Routers and Switches using different show commands

oConfigured EIGRP basic configuration, load balancing and variance, stub, authentication and redistribution

oImplemented OSPF initial configuration, authentication, stub, redistribution and virtual link

oConfigured a switch considering STP, Trunking, Inter - VLAN Routing, and VTP

oConfigured BPDU Guard, BPDU filter, port-fast, uplink fast, backbone fast of spanning tree

oAnalyzed and troubleshot Cisco Routers and Switches in LAN/WAN scenario

oSecured ports using Port Security and Authentication to prevent unauthorized access to the network
