@josvanegas

Senior Mainframe Consultant.

At Minsait / Santander Global Tech, I collaborated with business and technical teams on Santander USA Bank’s Gravity Migration, managing batch execution and validating migration requirements.

I also designed and developed an in-house tool to add masked production data to a pre-production environment for testing, and performed and validated DB2/Oracle delta data migrations.

Across banking and retail projects, I’ve worked on mainframe development, modernization, migration, testing, and production support. My experience includes COBOL, JCL, CICS, DB2, and Micro Focus technologies.
