Project 1 : Foundation Data Store
Client – Chevron Corporation, Houston, Texas
Role : ETL Datastage Developer
The FDS Target architecture is intended to describe the Common Data Architectural
design principles required for the Managed Integration component of the Upstream Data
Foundation that supports MCBU applications. The FDS target architecture for the
Managed Integration component of the MCBU Upstream Data Foundation will describe
the preferred model to use to integrate data from system of records, perform change
data capture, and ensure transaction integrity. In addition, it will perform
rationalization of master data, provide data quality filtration and business transformation,
shape data based on conformed entity models, and finally ensure data is formatted for
consumption based on use cases.
Responsibilities :
 Define the ETL Architecture
 Create a centralized data hub that is reliable and can be accessed by MCBU for
effective decision making
 Analyze and Understand the FDS Business Requirements
 Develop the IBM WebSphere Data stage Interfaces/ Components
 Develop the Sequencing mechanism to integrate number of datastage jobs
Pertaining to same business function.
 Shell Scripting in UNIX to schedule the jobs using Crontab.

3. Certifications
 Test, Deploy and Schedule the ETL jobs
Project 2 : Data Quality Management
Client – Chevron Corporation, Houston, Texas
Role : Lead Technical Analyst
Responsibilities :
 Build complex SQL queries and Datastage jobs to feed various Data Quality
Dashboards and reports and check on any discrepancy in the flow of data among
various systems.
 Focus is on ensuring that a program operates on clean, correct and useful data without
any inconsistency throughout Operational, Staging and DataWarehouse layer.
 Discrepancies in data are tracked and solution is proposed and follow up with the BA
so as to rectify the issue.
 Developed datastage jobs to integrate data from various systems to gain clear
understanding of data flow among various external/internal systems.
 After doing the root-cause-analysis ,if the code requires modification to be done in
accordance with the business requirements, the modified code is migrated after doing
thorough testing.
 Approval of DMR requests after validating the scripts successfully in appropriate
databases so that it can be further executed and implemented in Data Model
Project 3 : Runtime Support & Maintenance
Client – Chevron Corporation, Houston, Texas
Role : ETL Datastage Developer
Responsibilities :

loading operations using various databases, flat files etc.
 Developed Sequencing mechanism ie, Wait-For-Files to sequence the jobs
 Shell Scripting in UNIX to schedule the datastage jobs using CRONTAB.
 Monitor CPU Utilizations consumed by jobs and maintaining health-checks of
database
 Ensuring the databases are up and running and users are able to access various
applications.
 IBM Certified Designer Cognos 8 BI Reports.
