I'm a dedicated Oracle Database Administrator with nearly five years of hands-on experience managing large-scale Oracle environments (9i–19c) for international clients. I specialize in installation, patching, monitoring, RMAN backups (disk and tape), disaster recovery planning, on-call support, and automation scripting. I have practical exposure to RAC, Data Guard (foundational), GoldenGate (assisted), and upgrading databases, with a focus on high availability and performance. Beyond core DBA work, I collaborate with business teams to deliver SQL-based reporting, data migrations using Data Pump, and storage management. I enjoy building reliable automation and sharing knowledge with colleagues across borders to improve operational efficiency and data-driven decision-making.
