PROFESSIONAL EXPERIENCE

 

May-2012 – Present

Moody’s Corporation

·  Developed several jobs/transformations using PDI 4.4.3 to automate and to assist production support in permission changes to iFM(Internal Financial Matrix) application. Prior to implementing this process,  Corporate Financial Group (CFG FM) Permissions was very inconsistent with the current business practices and the developing regulatory environment. The process needed excessive helpdesk/production support calls and delays in carrying out routine credit work.

In order to trigger this PDI job, this process just needs a excel file, which will contain cleanup related information, in a designated shared location. Once the file  is placed a Control-M job will trigger this PDI job to Add, Delete, and Update permission related information in several Sybase and Greenplum databases, for single or bulk permission changes. At the end of a successful completion an email will be sent out to production support with the “User Permission Report”, being generated using  Pentaho BI Designer tool, as an attachment.

          This scripts will serve as a tool for production support to easily update   

           permissions.

 

·  Developed PDI job to delete records that are older than 60 days from several database log tables.

 

·  Used different types of input and output for various data source including table, text, csv, stored procedure and Excel files.

 

·  Developed several jobs to loops through between two files in order to gather appropriate rating and portfolio related data and email the information to the specific portfolio manager. Before sending out the email the job will check for valid email id, any unknown mail id’s will be replaced by “deftoEmaailAddr” value. It also checks with the opt out list to check if any of the manager has been opted out, if yes will get the alternate mail id.

 

·  Developed a pentaho mapping using Javascript so that this mapping can be used in 10 different jobs, the purpose of this effort is to avoid repetitive steps and for easier maintainability. The purpose of this ktr is to assign corrent flag for viewing Private/Public data in several rating applications.Private Data that has been flagged as viewable for a set of MIS employees only.Public Data that is viewable by all Users of Moody’s Financial Metrics – Banking (Internal and External)

 

 

·  Developed several Perl Scripts to feed HAVER Data into Greenplum database so that the data can be efficiently accessed using Sovereign ScoreCut Application. If business needs data for a  specific country, DLX export the data into an excel spreadsheet and then the data is converted into a tab delaminated output file in order to load into Greenplum using Perl scripts. Eventually these information will be used to print the Statistical Handbook. StatBook is a bi-annual publication that contains country statistics, economic and financial data, and forecasted data on Moody's-rated Sovereigns.

·  Developed several ETL Jobs/Subjobs/Transformations Pentaho(PDI/Spoon) to load data from Sovereign Database to SODA(Currently Moody’s use SODA to print StatBook. SODA application will retire once Sovereign Scorecard application goes live)

·  Developed reports using Pentaho Report Designer.

·  Developed numerous  PDI Process when I worked on various projects.

·  Developed several reports using Pentaho Report Designer tool.
