CAREER RECORD
Since Jan 2012 with GENPACT INDIA
Client Handled: GE
PROJECT EXECUTED
Title : TLM (Transaction life cycle management) Jan ’12 to till date
Client : GE Capital
Business Involved: GECA CASH, EFS, CRE, TREASURY, EMEA, EMEA2, GECA2, HQ and CAP INI
Domain : Finance
Role : Consultant
Environment : Development, Production Environment and System Integration Testing (SIT) Environment
Tools Used : Informatica 9.5, Oracle, UNIX and BI Reporting tool.
Scope : General Electric (GE) is an American multinational conglomerate corporation incorporated in New

segments: Energy, Technology Infrastructure, Capital Finance as well as Consumer and Industrial.
TLM (Transaction life cycle management) is a Reconciliation tool, which helps to monitor,
manage and enrich transactions throughout their lifecycle, from inception to settlement, and is
capable of extending the process to include external parties when required. It supports an array of
reconciliations requirements, from integrated cash and securities reconciliations through to generic,
inter-system reconciliations.
Businesses are doing their reconciliation on different frequencies (Daily, Monthly, and Quarterly). For
each business, Data has to be pulled from source systems and load the data into TLM as per
frequency. While loading the data into TLM, we use business logic to transform the data.
Roles performed:
• Extensive experience in Extraction, Transformation, and Loading (ETL) data from varied sources
into Data Warehouses and Data Marts using Informatica Power center, Power Mart (Repository
Manager, Designer, and Workflow Manager).
• Having good knowledge on different source systems like DB(Oracle, SQL server), Flat files(Fixed
width, delimited)
• Created Mappings Reusable Transformation, Mapplets, sessions, Reusable sessions, worklets and
workflows.
• Having good knowledge on SFTP process and deployment activities.
• Involved in all phases of SDLC.
• Good Knowledge on Data Warehousing concepts like Dimensions and Fact tables.
• Status Reporting and interaction with onsite testing team for removing gap between client
expectations and testing capabilities
• Having good experience in development and support systems.
• Designed and maintained design document and process logic documents.
• Developed Scripts for file monitoring, SFTP, splitting the files and mail notifications,
• Used Informatica Transformations like Filters, Aggregation, Joiners, Expressions, and Source
Qualifier.etc.
• Performed unit testing on various development mappings.
• Tuning the Mappings and sessions for better performance.
• Handling KT calls with BI team and Support team.
Classification: Genpact Internal
PROJECT EXECUTED
Title : Automation Control Solutions Central Processing System Apr’10 to Nov ‘11
Client : Honeywell, USA
Domain : Manufacturing
Role : ETL Developer
Environment : Development and System Integration Testing (SIT) Environment
Tools Used : Informatica 8.6.1, Oracle, UNIX.
Scope : The Honeywell CPS Data team to be extract and load the data from the various sources like Oracle,

time it is very important that we have a common reporting structure for the data management of all projects within
the program. We leverage the same utility database as with the data processes and centrally locate all project plan
details in a central set of tables and provide reporting to the deployment leads, data fil’s, data leads and full data
team for activity management, follow-up, and issue resolution.
Roles Performed:
• Build the Acquire and Localize processes based on mapping documents and direction from Data
Leads, Super Users.
• Involved in new object development we have never loaded before by developing Informatica
Mappings and Workflows.
• Add new data cleansing rules, Bug fix to localize based on data action inputs from data leads and
Super users inputs.
• Working Informatica PowerCenter client tools like Source Analyzer, Warehouse Designer, Mapping
Designer and Transformation Developer.
• Using most of the transformations such as the Source Qualifier, Application Source Qualifier,
Expression, Aggregator, Connected & unconnected lookups, Filter, Router, Sequence Generator,
Sorter, and Joiner.
• Using Developed SQL scripts for business data loads.
• Imported data from various Sources transformed and loaded into Data Warehouse Targets using
Informatica client Tools.
• Using shortcuts to reuse objects without creating multiple objects in the repository and inherit
changes made to the source automatically.
• Using Workflow Manager for workflows and session management, Database connection
management.
• Optimizing Query Performance, Session Performance.
• Delivering objects for client that is correct an on time.
• Prepared the Documentation to describe program development, logic, coding, testing, changes and
corrections.
• Transfer the data from non-SAP systems to SAP R/3 systems by using LSMW.
