Legacy Code Modernization | COBOL | SAS | JCL | Mainframe Expert
Is your organization struggling to maintain or modernize mission-critical systems running on COBOL, JCL, or SAS? I specialize in legacy system transformation—bridging the gap between mainframe reliability and modern development practices.
With over two decades of experience in both government and private sectors—including 8 years as a GS-12 Federal Computer Specialist—I bring deep expertise in mainframe programming, Medicare/Medicaid fraud analytics, and legacy financial systems. I don’t just understand legacy technologies—I’ve mastered them in high-stakes, data-intensive environments.

TSO/ISPF, MVS/ESA IBM 3090
Mainframe SAS (extraction, analysis, audit reporting)
Legacy-to-modern data migration
Large-scale batch processing and job optimization
🔧 Modernization Strengths:
Refactor COBOL/SAS for performance and maintainability
Reverse-engineer legacy code and business logic
