Project : Point Of Service (POS) Logging
Analysis
Role : Technology Lead
Sprint POS is a system features the Sprint Point-Of-Sale application, which
runs in all Sprint retail stores. This software automates sales by enabling
comprehensive functions vital to the Sprint retail marketplace, such as
reporting, processing of returns, sales, discounts/exceptions, and receipt
printing and configuration. There were huge amount of data flow of the logs
from different servers about the transactions at different stores
Nationwide. This POS primarily works out the type of exceptions that are
frequently occurring at the sites and also reduce the overhead of the
exceptions and recommends some best solution to the system.
Responsibilities:
V Involved in gathering the POS transactional Logs and analyzed for
the logs for developing Map reduce program.
V Installed and configured the Hadoop, HDFS in Linux Machine.
V Analyzed the requirements from the customers and participated in
Agile.
V Experienced in writing the Map Reduce Program by using various
Apache API for reading and analyzing the transaction logs.
V Involved in writing the hive queries for analysis on the structured
data in the output folder of HDFS.
V Experienced in integrating hive and HBase for better performing the
Map reduce algorithm.
V Involved in clustering of Hadoop in the network of 20 nodes one
making the master and rest as slaves.
V Tested a sample of raw data and executed performance scripts and
turned over to production.
V Past 2 years' data is collected from RDBMS (Oracle) and pushing
into Hadoop using Sqoop.
V T logs are pulled from log server and stored in the FTP server
hourly wise; this data is pushed into Hadoop by deleting data in
the FTP server.
V Data was pre-processed using MapReduce and stored into the Hive
warehouse.
V Conducted KT sessions on Hadoop framework and Map Reduce Algorithm.

Client : Data Cash, UK ( Offshore India) April 2011 to July 2011
Project : Translation System
Role : Java Team Lead
DataCash, in addition to being acquired by MasterCard, has also
over the last few years acquired many other payment processing
companies. The above has resulted in a situation where DataCash now
has multiple active processing gateways with merchants processing
actively via all of these gateways. This fragmented 'architecture'
does not allow MasterCard and DataCash to fully leverage the assets
and merchants it has inherited through the acquisitions. Cross sell
of services into merchants are limited by the fact that not all
merchants are integrated and processing through the primary
processing platform i.e. Data Cash Payment Gateway Migrating
merchants to the central platform is not easy as the interface and
messaging to each of the platforms are different. As a result, the
investment from the merchant to reintegrate to DataCash Payment
Gateway is very high and as a result we have seen resistance. The
long term objective of this project is to migrate all processing
centrally to DataCash Payment Gateway with minimal impact or effort
required from the merchant. The extent of the impact to the
merchant should be configuring a change in URL and possibly IP
addresses.

and Lines of credit products, the relationship pricing model will calculate
prospective net income (spread + fees) and respective returns for the full
contractual life .For all other products prospective revenue will be
