What I'm looking for

I’m looking to lead enterprise modernization—mainframe integration, ETL/data warehousing, and financial/Yardi reporting—driving measurable performance gains while mentoring global teams through digital transformation.

I’m an Enterprise Technology Leader specializing in mainframe modernization, data integration, and digital transformation across banking, insurance, financial services, and real estate. With 25+ years of experience, I focus on turning legacy complexity into scalable, analytics-ready enterprise ecosystems.

I’ve led enterprise modernization initiatives integrating IBM Mainframe environments with distributed platforms, SQL Server ecosystems, and cloud-based analytics. I design and implement ETL and data transformation solutions that migrate data between Mainframe, SQL Server, Oracle, AWS, and Azure to support enterprise reporting and data lakes.

My hands-on expertise spans IBM z/OS technologies including COBOL, DB2, CICS, IMS/DB, VSAM, JCL, CA-7, Changeman, XPEDITER, FileAid, and Eztrieve—supporting mission-critical, high-volume transaction processing. I’m especially known for batch optimization, enterprise reporting delivery, and compliance-aware delivery in SOx/SOC1 environments.

I’ve driven large-scale efforts such as leading global onshore/offshore teams and modernizing Yardi Voyager production/test environments across Americas, EMEA, and APAC. From executive dashboards to investor and operational analytics, I build reporting platforms and automation that reduce manual effort and improve performance.
