The God of JPA! 👍🏻 After taking the course once with a light heart, I feel like I've become a little more familiar with JPA, which used to feel so distant. He also points out things that are frequently used and things that are not used in practice, and I think it's really valuable 💎 knowledge that you can only get from an active development team leader. When I challenged myself with development, unlike other fields, there were no guidelines 🧭 on where to start and where to go, what is needed, and how to learn, so I think I've been lost a lot. However, after taking Kim Young-han's course, I've found a direction and can plan my future studies. Then, I'll continue to instill JPA knowledge💉 and see you again in another course. Thank you 🙏🏻
