About Me

I am a Senior Database Professional, Trainer, and Consultant with extensive hands-on experience in Oracle, SQL Server, and PostgreSQL database administration.

Over the years, I have worked in production-critical environments, handling high-availability architectures, performance tuning, database migrations, and disaster recovery solutions. I strongly believe that real-world DBA skills come from practical exposure—not just theory—and this belief is the foundation of everything I do today.

Oracle Database Administration (Single Instance, RAC, Exadata) and Performance Tuning
