Mainframe Release test management and automation lead

Responsibilities:

• Create and maintain JCL Libraries across 8 platforms/32 environment (PROC and PARM/DICT control cards) for each new quarterly/monthly release.
• Update control cards, library members, and preserve file cuts, as needed, to maintain environment integrity.
• Support CAST process and apply account files during environment refresh process
• Execute Environment Refresh activities, including but not limited to data-masking, updating processing date tables, generating and sending driver files, applying recent file cuts, loading accounts (pare down or full), and executing CICS jobs in Mainframe.
• Batch Processing. Promote/Demote and validate Change Man requests (pending appropriate approval) for QA code deployment. Cycle preparation to include set-up of jobs and submission of file inputs for upcoming batch runs. Execute jobs for batch processing and monitor to completion. Troubleshoot/triage abends or job failures and work closely with AD/Prod support/Test teams to drive towards root cause identification and resolution
• Provide all BAU or special request outputs to downstream applications and co-suppliers via file transmission or email notification.
• Provide on-call, weekend, and ad-hoc support for Break/Fix requests or urgent defect and escalation, as well as special Standalone requests (i.e. server migrations, file exports, data refreshes, etc).
• Automate the batch run using REXX and that saved 500 hrs per week for cycle run. I have been awarded for the same.

Mainframe application Migration research and development

Responsibilities:

• Worked on migration project involving 13 complex fraud detection applications, moving mainframe code to Java platform. To prepare BRD, Analyze the entire flow structure (Start of input until it gets to output) of all the applications to decode COBOL, assembler, DB2, IMS, REXX, Eastrive programs to a field level mapping.
• Then Plan to migrate the connectivity from FTP/ NDM and to establish new connectivity/ interface with new application.
• Explain the business and restrictions on using applications. Allocating resource and budget. This high level documentation is passed on to JAVA developer for further processing.
• Also coordinated the project with all stakeholders until completion
• Played key role in conversion. Successfully converted 3 applications to JAVA and Hadoop platform within a year. Met the deadline on Confidential without any effort slippage.
• Performed the Systems Development Life Cycle functions related to integrating the new Homestead modules into the existing Systems.
• Analyzed the existing COBOL programs, Jobs, DB2 Database of the Integrated System.
• Created Functional Designs from the Business Requirement Documents.
• Participated in the functional Design/Detail Design Review meetings.
• Created system Flowcharts using VISIO. Designed/Coded new programs using COBOL and SQL for the Homestead module of the Integrated System.
• Designed Easytrieve Reports for the Homestead Module.
• Worked on MQ channel to create an interface with vendor application like EWS (Early warning system) and Confidential . So that any Confidential the data(s) are dropped in MQ channel, BOA’s batch job will pick the data using FIFO methodology to process them and vice versa.
• When customer uses online web based transactions, the information’s are been passed on to mainframe CICS using CTG interface.
• These transactions gets collected in GLOM file and it has collection of all transactions processed for a day. Based on ABEND queue, errors are identified and debugged using IBM debug. The fix will be implemented after a test transaction placed via web.
• Played a key role in meeting a short deadline for code deployment. This is for increasing the master copybook layout for one of the major application. Have successfully compared the load module (LMC) before and after copybook changes. Also have deployed more than 5000 impacted modules (JCLS/PROCS/SYSIN/PROGRAMS..Etc.)

Mainframe support analyst

Confidential

Responsibilities:

• Provided 24/7 support for fraud applications.
• Responsible for analysis, code changes, scheduling and maintaining JOBs, creating reports and defect tracking.
• Tracked jobs using CA-7 scheduler. Analyzed the job log using SAR and resolved production ABENDs; performed impact analysis to resolve user queries.
• Used FILE-AID to create and modify VSAM (KSDS), PDS, and PS. Used TSO/ISPF utilities to create and Maintain PDS, PS, etc. and to monitor Spools and to migrate files from one region to other regions.
• Analyzed, designed and created new JCL JOBs, PROCs for daily, monthly & yearly Reporting purposes.
• Performed Root cause analysis to identify the cause of issues in the Test/Production environment by the team during SIT, UAT & implementation.
• Designed, coded and tested COBOL/Assembler/DB2/IMS program changes before implementing in production.
• Also have worked on CICS abends like ASRA/FNIF/AICA etc and provided timely fix to resolve the issue in production online environment.
• Engaging the interface partner in bring them on call to fix the issue in case of dependency with Up/Down stream applications.
• Have successfully worked on critical abend in an assembler program, further connects to an in core table. Spotted the issue and corrected the called program’s linkage section. Also have reduced the CPU usage for the program by minimizing the redundant code lines.

Mainframe Design Lead

Confidential

Responsibilities:

• Created mainframe modules and using COBOL, JCL, DB2, ISPF, TSO, FileAID and Endeavor as part of a four-member development team.
• Aggregated data from tables, VSAM files, and flat files on a mainframe team of fifty system analysts, QA engineers, DBAs, and software engineers.
• Wrote Technical Specification Documents (TSDs) for each assignment including a description of proposed changes, expected effects, and sample code to upload to the project SharePoint site.
• Coded mainframe development assignments in COBOL, modified tables in DB2, created job cards in JCL to run batch jobs, and modified online screens using CICS.
• Performed regression testing, system testing to gauge system performance
• Created Unit Test Documents containing test case procedure, data sources, results, and screen captures highlighting input and output data, indicators, and system display statements
• Supported the migration of modules into the production environment using the Endeavor tool by packaging the modules, submitting the package to verify the return code, and casting the package to enter the staging region
• Implemented changes to the communication interface between the mainframe and web space which added new client data fields and indicators while verifying incoming back-end data against the front-end
