  • Database Management: Manage data and execute complex queries using DB2 and SQL.
  • Independent Research: Independently analyze system behaviors and conduct thorough design reviews to identify potential improvements or risks.
  • Collaborative Development: Partner closely with developers to refine technical stories and requirements within an Agile environment. Ability to understand API driven cloud applications and collaborate with modernization teams.
  • Debugging & Troubleshooting: Perform end-to-end analysis and debugging of production issues, including the ability to look deeply into system logs.
  • AI Integration: Use Copilot and other AI-assisted tools to facilitate code research, analysis, and maintenance tasks.
