Role Developer

Description:

SABER project creates an environment as production environment. In this environment, the testing will be done as such in production. This project helps to detect the problems which may encountered in production environment by testing the same data in the environment created by Saber. The data is extracted from high stream and the data is validated, processed and manipulated to derive different fields and loaded to the appropriate tables. This process is carried out in SIT, UAT and also in Saber production environment. The data is verified and the process carried out in production environment. The future projects changes can also be checked here before starting the project phases which will be time consuming.

Project # 6

Project HE Subservicing

Client Bank of America

Period July 2011 to February 2012

Role System Engineer

Description:

HE Subservicing creates a testing environment as like SIT and UAT .If the High environment is carried out with testing of an application,the other application can be tested in the environment created by HE Subservicing. The data is accomplished by either receiving a feed from or extracting data from various source systems and manual systems of record (SORs).

These feeds originate from a variety of credit systems running on a number of different platforms. This data will be tested and loaded into the data mart for analysis and reporting. This project creates a testing environment for this data same as High environment.

Responsibilities:

System and Requirement analysis of the application is developed.

Discussions with System Architects to prepare the System Design Document and get it approved.

Used SQL to retrieve Credit card details stored in DB2 tables.

The environment is created in same way as SIT and UAT and versioning of files and tables are in sync with the original environment using REXX Designed tool .

Prepared test scripts and gave knowledge transfer to testing team in order to facilitate System Integration, Performance and Regression testing in testing environment.

Performed performance measures by different process and made query tuning to attain good response time.

Implemented code to production.

Post Production Support.
