GCATs App Migration

We provide development & support services for GCATs, one of Citi's core financial tools.

Our Work

Our Java Lab developed and implemented many varied enhancements to GCATs including the PL/SQL to Java migration of the tool’s principal modules. For this task the team did a global assessment of the system and carried out a project impact analysis which included the system’s technical documentation and several performance tests. We continue providing production support services for Citi’s internal users as well as migrating other modules to Java.
