Cihan Gedik

I have extensive hands-on experience with both PostgreSQL and Oracle Database, Oracle EBS Administration, particularly in production and enterprise environments.

PostgreSQL:

I have worked with production-grade PostgreSQL databases running on Patroni-based HA architectures, managing high availability, failover, replication lags, performance tuning, and daily operational support. My experience also includes diagnosing issues such as excessive temporary file generation, optimizing functions, and ensuring stable replication across nodes.

Oracle Database:

My Oracle background is very strong. I previously supported nearly 100 enterprises through a consulting company, delivering end-to-end DBA services. Over the years, I have performed thousands of database installations, configurations, migrations, and performance optimizations. I also have deep expertise in Oracle RAC, Grid Infrastructure, backup/recovery, and troubleshooting complex production issues.

Other Databases:

While my primary experience is with Oracle and PostgreSQL, I am fully open to learning and working with other relational databases as needed. I adapt quickly to new technologies and enjoy expanding my database skill set.
