CRAWLING | MAY 2015 - PRESENT | BANGALORE

• Working in an excellent team on Big Data ,Large ScaleWeb Crawl and

having in depth knowledge of Browser/Web Server interaction.An

integral part of my role is large-scale web data crawl and extraction

using cloud computing andmachine learning techniques.

• Design and development of various issues related to production.

Mainly deals with entire production pipeline. Major contribution in

various stuffs like Riak, Redis, ElasticSearch, RabbitMQ, Resque etc.

• Working on ElasticSearch, The project mainly deals with building an

API for product and pricing intelligence and indexing each of the fields

of crawled data for a comparison. We are using ElasticSearch for

efficient text-searching from the large-scale data, which is nearly

reaching upto EB scale in our storage.

June 2012 - April 2013| Silchar, India•Worked withDr. K.L Baishnab on information retrieval for large scale data based onHadoop Framework.

• Research onMobile Cloud Computing.

MASTER THESISJune 2014 – May 2015 | NIT Silchar, India

In thisproject,wepresentacircularmetadatamanagementmechanismnamedDynamicCircularMetadataSplitting (DCMS).

DCMS preserves metadata locality using consistent hashing as well as locality-preserving hashing, keeps replicated metadata

for excellent reliability, as well as dynamically distributesmetadata among theNameNodes to keep load balancing. NameNode

is a centralized heart of the Hadoop which keeps the directory tree of all files and thus failure of which causes the Single Point

of Failure (SPOF). DCMS removes Hadoop’s SPOF as well as provides an efficient and scalable metadata management. The

new framework is named ‘Dr.Hadoop’ after the name of the researcher.

To deal with small files, we built Hadoop ARchive Plus (HAR +) and put in on the top of Dr.Hadoop which is an updated

version the Hadoop ARchive.

ACADEMIC PROJECTS1. Design and Implementation of Interactive Speech Recognizing English Dictionary [B.TechMajor Project]

It’s a software interface which will recognize the word spoken by the user using the microphone and the corresponding

meaningwill be delivered by the computer through the speaker.It represents the procedure and logic for implementation

of a software application that uses the technology for recognition of Speech to Text and Text to Speech synthesis.

2. Effective Countermeasures for Cache Timing Attacks on AES

The project describes several software side-channel attacks based on inter-process leakage through the state of the

CPU's memory cache. This project proposes an algorithm which disables the cache memory for a certain period of time

.This would make the AES impregnable to cache timing attack.
