Platform : Hadoop.
Technologies : Java, Hbase, Solr, MapReduce, Spark, Flume.
Duration : Nov’14 to– Till Date
Description : ANR is a back office umbrella application of DB. This application
collates trade information from various application within DB and will do cross product
valuations to compare trades and provide a summary of trades(match/mismatch) and trades
measure mismatch.
The goal of this project is to build an Automated Number Regression Testing tool to compare
two different builds of Risk Valuation System for a population of trades.The tool leverages the
capabilities provided by Hadoop Ecosystem etc. This umbrella application covers multiple
business which are
 HSV(Historical Simulation of VAR-Value
at risk)
 CPX(Counter Party Exposure)
 EBA(European Banking Authority)  HSSV(Historical Simulation of SVAR-
Stressed VAR) IPV(Independent Price Verification)
 PV(Present Value)  MR(Model Reserve)
For each business, trades are compared/evaluated against data generated by 2 environments
i.e. PROD CPX vs UAT CPX,PROD HSV vs UAT HSV,etc
