Reverse-engineered 20+ COBOL modules across enterprise banking workflows, analyzing business-rule dependencies, metadata mappings, and transaction-processing behavior to accelerate modernization efforts. Engineered backend service-layer workflows for COBOL-to-Java modernization, integrating QSAM, VSAM, DB2, and IMS data pipelines through reusable DAL-based architectures. Debugged complex metadata-driven transformation flows involving COBOL REDEFINES, OCCURS, and COMP structures, ensuring accurate data expansion and object population across Java processing layers. Resolved 15+ critical output-parity and data-transformation defects through structured root cause analysis across metadata, mapper configurations, DAL integrations, and service-layer business logic. Implemented SLF4J-based structured logging and intermediate validation checkpoints, significantly improving debugging observability and reducing issue-isolation turnaround during migration validation cycles. Executed output parity validation between legacy COBOL systems and modernized Java services by analyzing generated output artifacts and eliminating functional regressions across migrated workflows. Enforced clean code standards via structured peer code reviews, identifying anti-patterns and improving long-term maintainability of migrated backend services.
