Message

At Oracle Corporation Ltd, I administer and optimize Oracle Autonomous Database environments across high-security enterprise platforms, delivering 99.99% database uptime. I also streamlined patching processes and automated deployment workflows, reducing maintenance windows by 30%.

At Hamilton Holding, I designed database architectures across PostgreSQL and SQL Server environments and managed PostgreSQL RDS and Azure managed SQL Server instances in hybrid cloud environments. I implemented replication and failover strategies and automated infrastructure provisioning using Ansible, Terraform, and CloudFormation.

Earlier, at Datwyler, London UK, I led migrations of critical databases to AWS Cloud, reducing infrastructure costs by 20%, and upgraded Oracle databases from 11gR2 to 12c. At Sportingbet PLC, I migrated databases to RAC and Linux Exadata environments and implemented Data Guard for continuous data protection.
