• Working as a mainframe software developer.
• Working closely with SMEs and Project management Team in the design and initial setup.
• Coding of jobs using JCL with embedded complex SQLs to extract the 20 million customers’ and agents’ data records into TAPE files, to log into and place/FTP the files on/to the UNIX server.
• Also developed a Native PL/1 - DB2 stored procedure. A Java service will hit this SP for every 15 mins to identify and pull the current updates done to customers’ and agents’ data on mainframe DB2 server side and reflect the same on salesforce side.
• Preparing unit test cases and documenting the test results.
• Drove test case results review meetings with project team, Handling business walkthroughs and Demos for the new functional implementations.

Mainframe Software Developer

Responsibilities:

• Worked as a mainframe software developer.
• Developed a COBOL DB2 program with complex SQLs to terminate/remove the prospects/ex-customers records who are also active customers with respect to another agent.
• The program gets triggered through a daily job scheduled to run 10 times per day terminating 50k records per each run. Coded the job in such a way that it will notify the service team through an email once all the 16 million records get terminated. This way we can request the scheduling team and get the job unscheduled.
• Handled all levels of testing from unit test, system test, performance test, pre-prod and production.
• Provided early life support and monitored the job until all the 16 million records get terminated.

Environment: IBM Mainframe, COBOL, JCL, DB2.
