What I'm looking for

I seek senior DBA roles managing Oracle/Exadata environments with emphasis on performance, migrations, 24x7 production support and knowledge transfer.

I am an experienced Oracle Apps DBA with decades of hands-on administration, performance tuning, upgrades and migrations across Oracle versions from 7 through 19c, Exadata and Oracle Applications R11/R12.

I have led implementations, datacenter migrations, performance projects and 24x7 production support for large enterprise clients including Odebrecht, Yamaha, Cielo, Pão de Açúcar and others, and worked extensively with Oracle middleware, WebLogic, SOA Suite, Fusion and Exadata technologies.

I combine deep technical skills (Oracle, SQL Server, MySQL, EMC storage, multiple UNIX/Windows platforms), strong documentation and training experience, and customer-facing coordination to deliver stable, high-performing database and applications environments.
