Sr. J2EE Consultant

• Online Test Data Management Application
• a. The application fetches and displays the test data, ready to be used, for development and testing teams.
• b. Includes SQL DB queries and web service calls.
• Impact Analyzer Application
• a. Tool allows user to input list of modules, main functionalities and sub functionalities of the home depot online application, and allows to manage the impacts between them.
• b. This helps the testers and developer identify impacted areas when there is code change in a particular functionality and regression test the impacted areas.
• Knowledge Evaluation Application
• a. Tool allows user to evaluate his proficiency in his domains, by going through evaluation test.
• b. Manager will be able to see the results.
• c. Workflow for Requesting additional attempts after user exhausts his predefined attempts is also available.
• Environment Dashboard Application
• a. The tool has a batch which tracks the status of order across all systems of order life-cycle.
• b. Batch architecture is used to build batch for triggering test orders each 2 hours.
• c. Message Driven Bean is used to listen to the orders across all systems and store the order status and other key data required to evaluate the status of order.
• d. User can see the status of systems at any time on the dashboard web application he can also lookup for a particular order.

IT Analyst/ Module Lead

Environment:

Project: CLAS Data Management

Responsibilities:

• Extract data from Operational Database using JAXB annotations on existing Hibernate Component.
• Periodically extract data using java batches developed with USAA Enhanced Java Batch Framework.
• Schedule batches using Control-M, Shell Scripting and CTL tables.
• Developed EJB and web service calls for fetching data from multiple database.
• Developed common batch code for extracting data as flat files from DB tables using XML Configuration Manager Infrastructure and JDBC.
• Incorporated ERDC code to override the batch parameters from CONTROL-M
• Whenever the ERDC table has data with input parameter names, the inputs from Control-M are overridden and data from ERDC is used to run the batches.
• This gives the user capability to extract data with custom inputs. The need arises when the data is corrupted in the reporting DB and needs re-load from the batches. This often happens in the initial releases with frequently changing reporting requirements.
• Worked with Control-M in resolving successor/ predecessor dependencies and Batch Scheduling requirements.
• Developed batch code to cater the changing intraday scheduling requirements.

Achievements:

• Injected code in batches for controlling the execution of batches from ERDC Infra tables. ERDC tables are developed for easy access and controlling capability through UI for Admin or Business Associates.
• Appreciated for the design and scalability of the batches developed.
• Effectively interacted with ETL team clients who consume the extracts generated from the batches and helped in creating dependencies within the batches.
