What I'm looking for

I seek roles focused on Oracle database reliability, performance tuning, and large-scale migrations in collaborative teams where I can architect and optimize production database environments.

I am an Oracle Database Administrator with experience designing, installing, and configuring Oracle Database environments, including RAC, Exadata, and Standby systems. I have delivered performance improvements through SQL tuning, managed large databases (45TB+), implemented backups and recovery strategies with RMAN, and led upgrades and migrations to Oracle 19c.

I have supported 150+ clients across diverse environments, created 20+ environments from scratch (OCI and on-prem), and resolved complex issues in mixed stacks involving WebLogic, Tomcat, Windows Server and Linux. I hold OCP 19c and Data Guard certifications and focus on reliability, performance, and scalable database architecture.
