The environment consists of more than 1000 databases (Production, Pre-Production, Development, and QA) running on AIX, Linux, Windows and Oracle Cloud in different releases from 11g to 19c. I started the migration of the databases to Oracle Cloud. I offer Jenkins jobs for automated user and repository tasks; I install Oracle APEX, ORDS. I create shell scripts for the AO department. I offer 24x7 support, proactive monitoring performance, and availability.
