What I'm looking for

I’m looking for hybrid or remote opportunities where I can drive AI-driven modernization and cloud transformation, strengthen production support reliability, optimize batch performance, and automate manual monitoring—while being willing to relocate.

I’m a Mainframe Developer with 11+ years of experience in COBOL, JCL, DB2, and CICS, focused on production support, system optimization, and legacy modernization. I’ve consistently resolved critical production issues, improved batch performance, and strengthened system efficiency while reducing manual effort through automation.

In my recent work at TIU Consulting, I enhanced COBOL programs for core banking systems, designed and maintained JCL jobs, and resolved critical abends (including S0C7 and S322) to minimize downtime. I also optimized DB2 queries (15%+ improvement) and supported modernization initiatives such as API integration and cloud readiness, including AI/automation-assisted log analysis and issue detection.

Earlier roles strengthened my end-to-end delivery mindset across CICS online applications, VSAM file processing, data migration and testing, and refactoring legacy COBOL for maintainability. I’ve led batch optimization (20%+), migrated COBOL applications from Windows to Linux, improved job stability, delivered encryption and data security fixes, and contributed to release management in Agile/Scrum environments—grounded in Python-based production support automation and AI-assisted development.
