What I'm looking for

I seek senior roles focused on database reliability, cloud migrations, and team leadership in organizations valuing SLAs, automation, and continuous improvement.

I am a Senior Database Administrator with 18+ years managing enterprise databases across Oracle, DB2, SQL Server, Sybase, PostgreSQL and MySQL in mission-critical, high-availability environments.

I have led DBA teams in multinational outsourcing settings, delivered SLA-driven operations, and executed major datacenter and migration projects with zero downtime, achieving significant cost savings.

My strengths include performance tuning, backup/recovery, replication, disaster recovery planning, capacity forecasting, Unix/Linux scripting, and Oracle Cloud (OCI) implementations and automation.

I hold multiple Oracle certifications, have driven process improvements that reduced costs and recovered underperforming contracts, and I am pursuing a Postgraduate Diploma in Artificial Intelligence to expand my technical leadership in modern database and cloud architectures.
