While studying Spring Boot, we often settle for "as long as it works" and move on. The moment we are asked about the reason behind a single annotation or a specific structure, we find ourselves speechless. The reason our minds go blank when asked "Why did you design it this way?" during interviews or collaborations is ultimately because we relied on memorization rather than true understanding.


To solve these problems, we are launching the 4-week completion challenge for 『Bootcamp Backend Developer Edition with Spring Boot』. Let's read the assigned portions together and resolve any stuck points through questions. After completing the book, we plan to hold a Q&A-based seminar to discuss frequently asked questions, common misconceptions, and 2026 developer employment strategies.


In the AI era, what matters is not how fast you can write code, but the standards you use to understand and judge code and design. Through the "Bootcamp Backend Developer Edition with Spring Boot" complete reading challenge, transform your knowledge from "knowing it" to "being able to explain it"!

    What sounds good also looks good! Why can I hear your voice while reading this? lol As always, I felt that understanding is more important than memorizing. I will continue to eagerly look forward to your next videos and books!
