I have more than 25 years of experience working with DB2 and more than 30 years working in the Mainframe environment. I worked at Banco Galicia -one of the most important private banks in Argentina-, as a System Programmer and DBA for DB2 for z/OS, where I had the privilege of leading the System Programmers and Database Administrators teams for mainframe and mid-range environments. I currently work at Kyndryl (Poland), where I work as a DB2 z/OS SME, supporting the account of a major client with multiple locations.

Focused on obtaining and exploiting data to evaluate the capacity and improve the performance of the DB2 system, as well as on the exploitation of accounting data from applications, to improve their performance and optimize the use of processing resources.
