Company Name :

IGATE (Feb 2012 till date) for an Australian Mining Giant

01

Project Name :

Instrument binary data analysis using Big Data

Tool & Technology Used :

C++, Big Data, Hadoop Streaming and Pipes, MapReduce

An Australian Mining company has partnered with IGATE to extend research and development activities to India. Project is in Proof of Concept stage. In this work, Big Data technology like Hadoop MapReduce and/or Apache Shark may be used to analyze instrument data by running machine learning algorithms. Engagement is in Individual Contributor role.

Developed binary data transformer in C++ to decipher instrument binary data into plain text done thereby replacing commercial licensed software. Developed map-reduce programs in C++ using Pipes and Streams to analyze the time series data and run on Hadoop Platform. Linear regression is used as Prediction model for data analysis.

Learn and experiment with Spark platform to analyze the converted data.

02

Project Name :

DAS Data Logger at IGATE


C++, UML, Design Patterns, STL, Python Scripting, MS Project, JIRA, Confluence, Contour, Code Collaborator, GIT, RHEL OS, MongoDB, PostgreSQL, pymongo, C++ Boost, BSON, SWIG, Python UnitTest Framework, Agile, Scrum

DAS Data Logger application is developed to collect drilling instrument data which is of form key-value pair, from several sources reliably into a central database system. This data is used for analysis and visualization.

Worked closely with stake holders from off-shore and while at Melbourne & Perth, Australia in 2013, to carry out requirement gathering, planning and execution, user acceptance testing and deployment of software developed.

Played role of Project Manager for a team of 4 members as well as that of Technical Lead, doing project planning, execution and monitoring, identifying risks, resolving issues, assess & report project health on key metrics like schedule variance, effort variance etc and technical and user documentation.

In this project, the team was involved in design and development of several components.

An API in C++ that provides an interface to collect and serialize data.

A client developed around the API that can communicate with a backend application using TCP.

A backend multi-threaded application that manages communication with multiple clients, allows pooling of data and writing of data to the database. The service would run as a daemon on startup.

Command line utility in Python for customized querying of database and accessing database statistics in real time.

Demonstrated POC for data replication and fault tolerance in MongoDB using MongoDBs replication framework.

Compared and evaluated PostgreSQL & MongoDB and serialization techniques like Protocol buffer, Thrift and BSON.

Extended C++ communication library in Python using SWIG that enabled development of software in Python.

Company Name :

Nokia Solutions Networks (Feb 2011 Feb 2012)

03

Project Name :

Flexi Base Platform

Base Platform is one of the key components of Flexi Platform used to build IP based telecommunications applications and solutions. It provides basic services needed in all network element applications like directory services, hardware management services, IP services, security services and high availability services. The project required maintaining and enhancing Secure Command Line Interface (SCLI) module.

Played role of Scrum Master for a team of 8 members and gradually increased user story point velocity by 20% by better work break down and allocation of resources and reduced gap between ideal and remaining efforts by moderating sprint commitments.

Initiated and owned removal of critical and severe warnings/errors reported by static code analyzer Klokwork thereby increasing code quality.

Awarded Most Valuable Player for leadership skills displayed in the Sprint earning most story points.

Developed features for displaying terminal session information which was not previously available, secure file operations using setuid enabled binary over stdlib, configurable relative command line mode which was not previously.

Written a Shell command supporting tabular and multi-line output to display relationship between node(s) and the hardware unit housing it.
