About Youngmin (Eric)
Youngmin (Eric) Park began his IT career in 2012 and is currently working as a Senior Oracle DBA in South Korea. Holding an Oracle 26ai OCP and a SQL Professional (SQLP) certification, he has a strong passion for Oracle database engineering and performance tuning. He has hands-on experience with Oracle versions from 9i to 26ai, covering a wide range of database administration tasks. Currently, he is actively exploring the latest 26ai release, focusing on its new performance-enhancing features. He enjoys conducting a variety of tests involving operations, backups, migrations, performance tuning, and newly introduced functionalities. Youngmin is also an Oracle evangelist and the author of the blog ["내맘대로긍정 (On My Own Terms: Positive Management)"](https://positivemh.tistory.com), where he freely experiments and shares findings based on his own interests. His blog serves as a technical sandbox where he documents real-world scenarios, edge cases, and thought experiments for fellow DBAs and database engineers. His favorite saying is, "Knowledge is not to be withheld but to be shared."
