TECHNICAL EXPERTISE

  • Pitched IT4IT Epics for cost saving measures and technical transformations during Product Improvement (PI) Planning to broader audience including non-technical colleagues from organisation.
  • Improved performance of COBOL programs by optimising DB2 approaches, performance of COBOL programs measured by reduced Service Units. Strobe and DB2 Explain tables are key tools for identifying performance degrade.
  • Worked out effective job scheduling for completion of jobs within the batch window - adapted selective batch programs to be able to execute alongside CICS. Grouped / Separated jobs accessing multiple DB2 subsystems. The jobs dependencies and special resources are effectively utilised from TWS OPC.
  • DB2 database partition / sequence growth controlled by identifying unused sequences and reused them.
  • Contributed to technical design for multiple projects. For example, Migration of 4 policy administration systems to a single system, Mainframe re-platform, Migration of source code version management from SVN to Git (Azure Repos), Migration of customer communications built in legacy DCF / Script VS to modern Thunderhead
  • Created an optimised process for DB2 unloads to CSV format for various business necessities.
  • Achieved 95% SLA compliance for incidents resolution.
  • Lead the Problem Management activities, provided structural solution for recurring incidents by identifying the root cause of the incidents. This led to incident reduction up to 65% over the period of 2 years.
