Analysis, coding, testing and implementation of all the interfaces with mainframe applications.
Data communication interfaces coded using different protocols like TCP/IP, RJE, dial-up communications BSC, ASync. Client Access, TCP/IP Socket Programming.
Participation of the contingency disaster recovery tests in our hot site in U.S. annually for the critical bank applications.
