  • Working in an Agile environment at Vanguard, performed the design and development, of COBOL programs and related multi-step job to capture Offshore User IDs and convert them, for insertion into a DB2 table. A DB2 Native SQL procedure was also developed to convert the User IDs dynamically via Front-End Java programs. Prepared all necessary documentation to migrate the package into production.
  • Created and ran a multitude of DB2 Loads and Unloads to migrate tables from the SAT (System Acceptance Testing) region, to the IT (Integrated Testing) region.
  • Developed masking process for SSN data coming from the production environment to the test environment, along with associated job.
  • Enhanced the Grant processes to support Archive and Accelerator Only DB2 tables.
  • Wrote many REXX EXECs and CLISTs to automate and facilitate various processes for the IESS team.
  • Modified many jobs to support email delivery to our Offshore Partners. Although the change was repetitive, it required great attention to detail, so as not to impact current production processes.
