[Lv1] Spring Boot You Can 'Explain' in Interviews - Backend Development Answering with Experience

This is a backend development introductory course where you learn through understanding rather than memorization, and experience rather than theory. Instead of answering the interview question "What is JPA?" by reciting a Googled definition, this course enables you to give an experience-based answer that starts with "I've been through JdbcTemplate hell..." You'll directly experience the process of reducing pure Java ServerSocket from 30 lines to Spring Boot's 7 lines, and understand with your whole body "why we use frameworks." After 6 sessions, you'll have in your hands a working portfolio: a Todo List REST API implemented with Spring Boot + JPA.
