As a Senior Oracle Database Administrator and PostgreSQL DBA, I specialize in managing and optimizing enterprise-level database environments across leading financial institutions. At Crédit Agricole Bank, I work with Oracle Databases 10g–21c, pluggable databases, RAC, Data Guard, Exadata (X7, X8, X11), OEM, and RMAN, in addition to administering PostgreSQL Community and EDB platforms, including EFM for high availability. My role also includes managing Oracle E-Business Suite, database migrations, performance tuning, and OS administration across Linux, Solaris, and Windows Server.
Previously at First Abu Dhabi Bank (FAB1), I supported large-scale Oracle environments, including E-Business Suite R12.1.3, RAC, Data Guard, Exadata X5/X9, WebLogic, Grid Infrastructure, and AVDF, along with advanced RMAN operations and performance optimization on Linux, Unix, and AIX.
Earlier at QSIT, I managed Oracle Databases (11g–21c), GIS systems, Data Guard with DG Broker, Grid 19c, and complex RMAN tasks such as Live Duplicate.
I’m passionate about delivering robust database solutions and leveraging technology to meet business objectives. Certified in Oracle Cloud Infrastructure, I’m always eager to apply my skills to new challenges.
