What I'm looking for

I'm looking to contribute in DevOps, cloud operations, Oracle Database, or enterprise support roles where I can solve critical operational issues, support migrations, automate infrastructure, and continue growing with OCI, Azure, Terraform, CI/CD, and AI.

At Oracle, I deliver advanced support for Oracle Database and Exadata, diagnosing service-impacting issues and coordinating MOS SR escalations for a major banking customer.

I've supported complex investigations, root-cause analysis, proactive health checks, and Oracle Database 19c migrations from on-premises environments to OCI and Azure. My work spans RAC, ASM, Data Guard, RMAN, HA/DR, patching, upgrades, and post-migration validation.

Previously at DRÄXLMAIER Group, I administered business-critical Oracle Database environments, managed monitoring, incidents, changes, and documentation, and automated recurring work with Bash/Shell across Linux and Windows infrastructure.
