## About

```text
At NXP Semiconductors Germany GmbH, I designed and operated SQL Server Always On Availability Groups for business-critical production databases. I also planned geographically distributed replication and handled migrations, upgrades, and performance optimization.

At IBTECH A.Ş., I administered large-scale Oracle, Microsoft SQL Server, and MySQL environments. I designed disaster recovery for a 200+ TB Oracle Exadata Data Warehouse, performed Oracle RAC and ASM upgrades for more than 20 databases, and automated administration tasks with PL/SQL and T-SQL.

Earlier, at Turkish Economy Bank (TEB), I administered 400+ databases supporting core, internet, and mobile banking. I implemented RMAN backup and recovery procedures, performed database upgrades and migrations, and configured Oracle GoldenGate.
