I’m a dynamic, results-driven Database Administrator with 9+ years of experience in enterprise environments—6+ years in Oracle DBA roles and 3 years managing UC4 scheduling systems. I focus on dependable database operations and measurable outcomes, from uptime to faster incident resolution.

I’ve migrated 50+ databases across global data centres using RMAN and Data Pump, and I’ve led Oracle upgrades from 11g to 19c with near-zero downtime. I also implemented Active Data Guard to maintain 99.99% uptime and automated disaster recovery processes to cut manual work by 80%.

Performance and stability are core to how I work: I use OEM and SQL optimization to tune database performance (up to 35% improvement) and perform root cause analysis for high-impact issues. I build SOPs and run knowledge transfers so teams can operate with confidence and consistency.

I bring hands-on, cross-functional execution—working with Infra, Unix, and Storage teams to streamline operations. From RAC/ASM, patching, and user provisioning to cloud migrations (including AWS RDS) backed by rigorous testing protocols, I’m at my best delivering upgrades, migrations, and DR strategy in global delivery environments.
