CCNA (ROUTING/SWITCHING)[CISCO ID: CSCO12944479] Mar'2016 to Mar'2019 PROFESSIONAL EXPERIENCE

Giftson Info Tech Ltd.(NETWORK ASSOCIATE) Aug'2013 to Aug'2014 Worked closely with a Network Engineer, developed configuration review procedures, configured and managed router and switches. Configuring and Troubleshooting RIP,OSPF and EIGRP routing. Exceptional skill set in Cisco IOS base language. Configured ACL to allow only authorized users to access the servers. Implementation of NAT with a pool of public IP addresses Switching related tasks included implementing VLANS and configuring trunk on Fast-Ethernet channel Documentation of network including topologies, license, backup procedures and nodes using network diagrams, flowcharts San Diego State University (TEACHING ASSISTANT) Jan'2016 to Apr'2016 Helped undergraduate students in their lab for design of network layouts and configuration of network devices in gns3 network simulator and Cisco packet tracer

Taught the students about sub netting concepts, VLSM and categories of network IP classes Responsible for helping students in completion of their lab assignments on time PROJECTS

Communication between client/server using socket programming Jan’2015 to May 2015 Initiated communication between two client using sockets; Data sent from client to server, manipulated in the server and sent to the other client. Used SSH secure shell and for testing and successful testing and completion of project Why NET design with Isochronous and Asynchronous traffic support Jan' 2015 to May 2015 Why NET is an improvement over 802.11n with isochronous and asynchronous traffic support (QOS). Network performance was i vastly improved with the network design and operates in 40 MHz BW and compatible with legacy nodes Multi hop Multichannel Wireless Sensor Network Aug’ 2015 to Dec’ 2015 The network is divided into clusters with a cluster head for each. Gateway is the entry point for the network. The network has an improved addressing mechanism, data allocation, transfer and recovery mechanisms compared to normal network design Latency measure in inter process communication Aug' 2015 to Dec'2015 Developed a multiprocessor application in which the parent process creates a shared memory location and two children. The children will be designed to signal each other in a ping pong pattern storing the times at which they received the signals into the shared memory. Semaphore is used for shared memory protection Software Defined Network - Study of Open flow protocol Jan'2016 to May 2016 The Open flow protocol was extensively analyzed and a detailed report was prepared stating the working, applications and potential challenges of software defined networks while implementing it Mpeg Video Encoder and Decoder using Matlab Aug’2015 to May 2015 Encoder and decoder ware developed to encode a short video. Compressed using DCT transform temporal redundancies were reduced using motion estimation techniques. Decoding was done with motion vectors and difference frames. The aim of the project was encoding/decoding using MPEG video standards.
