2. Professional Experience:
Project #1:
Title : Data Science D2O
Client : Nielsen
Environment : Impala, Hive, Phoenix, HDFS, Map Reduce, HBase
Role : Developer
Description: This project willdigitize data science to align with the Nielsen vision to become more
digital. All Data Science tools are dependent on Global Factory Data being available in NDX.
NDX is uniquely positioned to deliver local and global insights into consumer behavior and product
sales across categories in nearly 100 countries. Nielsen’s powerful combination of deep data and
insights arms clients with actionable intelligence for their business planning. Our tools provide
clients with timely, flexible analytics, presenting a holistic view of the marketplace. Infusing digital
into data science to unleash innovation & provide cutting edge solutions for our clients. The major
implementations are CVCalc & Replica in Data Science.
CVCALC:
 Implementation of new robust methodology forCV calculation based on modelling approach.
 Improved data stability through minimized sample changes during sample re-designs and
annual updates and data precision through more robust variance calculations.
 Integrate tool with NDX and other tools within it improving calculation efficiency
REPLICA:
 Replica is a tool for calculating Relative Standard Error. Using a variance engine which is
based on bootstrap principles. It simulates thevariation associated withsample participation
by forming replicated samples where sampling units are giving variable rights to participate
in the sample.
 This tool willallow standard decision in compliancewith our WBS,in terms of sample design
and MBD reporting. And therefore will translate in better quality to our client deliverables.
Responsibilities:
 Interaction with client in gathering and understanding the requirements
 Involved in writing Impala queries to load and process data in Hadoop file system.
 Involved in writing Phoenix scripts to load and process data in HBase.
 Writing Shell scripts that are invoked by TibcoBW.
 Writing Map Reduce code for bulk data loading to Phoenix.
 Involved in integrating Hive and HBase for purpose of generating reports.
 Involved in team level meetings for knowledge transfer.
