About 6 years ago, when I had a stagnant career, I started pulling my weight after taking Young-han Kim's JPA course, and now I've reached a point where I'm evaluated as a high performer at my company.

Now, ahead of a job change where I'm scheduled to take on the roles of PM and Team Leader, this DB course was released at the perfect time. Even though I find backend development easy now, DB was always the area where I felt lacking, but this roadmap is truly resolving many of the concerns I've had in practice.

I would like to express my sincere gratitude to Mr. Young-han Kim for saving my career once again.
