At Vitor Tee How Siao Junior Tecnologia da Informacao LTDA, I founded an independent database consulting practice. I help corporate clients with database administration, optimization, migration, and Kafka-enabled replication.
I redesigned Microsoft SQL Server structures to receive Kafka-replicated data feeds and defined a repeatable migration process from Microsoft SQL Server to PostgreSQL. I also advise client teams on operational continuity, troubleshooting, and database support procedures.
At PDCASE Informatica Ltda, I administer Oracle development environments and develop and optimize SQL and PL SQL solutions for financial and mission-critical systems. I reduced a critical workload from approximately 30 minutes to 30 seconds through query redesign, indexing, and parallel processing.
I contributed to Banco da Amazonia core banking modernization and supported data migration, production systems, and application development for financial services clients. Earlier, at Facil Informatica, I developed and maintained corporate systems and supported legacy data migration and Level 2 technical support.
