At CTIS Tecnologia S/A, I support OpenVMS, Caché databases, IBM MQ Series, and IBM Message Broker for CAIXA ECONÔMICA FEDERAL. I also maintain Java applications, including the call management, INFOBANCO, and personnel management systems.
At Conselho Federal de Odontologia, I administered and developed Caché systems, maintained legacy MUMPS systems, and worked on database migrations to SQL Server and MySQL. Earlier, at Tecnisys Informática e Assessoria Empresarial, I coordinated a web development team and participated in systems including SII for FUNAI and the APEX BRASIL portal.
