Mainframe Developer

Confidential, IL


  • Performed analysis, design, and development for the Scorecard Remediation project.
  • Assigned to a new area to process the converting of legacy VSAM files to a DB2 table structure.
  • Worked on a project to read the new tables and build a duplicate of the VSAM record to use in a compare program to ensure the tables were being built with accurate data.
  • Supported the RTA/MLE process, a real-time claim adjudication and estimate subsystem.
  • Utilized skills in CICS, DB2, MQ Series, JCL, and COBOL, with a heavy emphasis in analysis and design.
  • Collaborated extensively with the DBA area to identify resource constraints and fine tune isolation levels to minimize contention.
  • Provided support for environment setup, installation, testing, and implementation of BCA releases 11.0, 11.1, 11.2, including DB2 table conversions and MLE throughput reporting.
  • Performed analysis, design, development and ongoing support for the major reconstruction of the ITS infrastructure involved with the BCA 10.0 release.
  • Contributed to installing all new components, creating test/cycle environments, identifying bottlenecks, streamlining to allow for concurrent processes, and volume testing.
  • Ensured the verification of all affected ITS processing components.
  • Served as an integral part of team involved in the initial BCA 10.0 release, converting a VSAM format to DB2 - ETL.
  • Handled setting up, data conversion, and loading of new databases as well as performance tuning.
  • Executed development depending a great deal on analysis skills involved in designing and tuning conversion processes to ensure a result that was accurate and efficient in its conversion.
  • Assisted with work on the subsequent 10.1 and 10.2 releases, including the unload, conversion, and reload of 6 billion DB2 table rows in 12 hours to improve overall system performance by a change to the partitioning algorithm.
  • Applied the above database changes to all test and cycle environments (eight platforms).
  • Helped extensively in a separation of test and production platforms by changing JCL streams to a procedure-based system with heavy use of symbolics to facilitate the cross use of procedures between test, cycle, and production environments.
  • Corrected problems in the online screen-based CICS system including changing of maps and programs based on BCA mandated enhancements.
  • Created an automated process, date and calendar system that automatically generated a file of future daily and weekend process dates catering for holiday and leap year factors.
  • Assisted other team members by offering debugging/problem solving skills.
  • Troubleshot problems and devised a solution based on limited or incomplete information.
  • Researched the IBM MQ Series for a new project involving real-time claim adjudication.
  • Attended HIPAA healthcare training seminar.
