[Lv1] Spring Boot You Can Explain in Interviews — Backend Development Answered Through Experience

This is an introductory backend development course where you learn through understanding rather than memorization, and through experience rather than theory. Instead of memorizing and reciting a Googled definition in response to the interview question, "What is JPA?", this course helps you give an experience-based answer that begins with, "I've been through JdbcTemplate hell..." You’ll personally experience the process of reducing 30 lines of pure Java ServerSocket code to just 7 lines with Spring Boot, gaining an intuitive understanding of "why we use frameworks." After six lessons, you’ll have a working portfolio project in your hands: a Todo List REST API implemented with Spring Boot + JPA.
