I felt like I had been using Spring Boot without truly understanding it. Although I had learned various parts here and there, I struggled to connect them all together. The examples of the underlying principles, combined with the practical code and explanations, have significantly deepened my understanding.

This is an introductory backend development course where you learn through understanding rather than memorization, and experience rather than theory.

Instead of reciting a Googled definition when asked "What is JPA?" in an interview, this course will empower you to give an answer based on experience, starting with "Well, I've been through JdbcTemplate hell..."

You will gain a deep, intuitive understanding of "why we use frameworks" by experiencing firsthand how 30 lines of pure Java ServerSocket code shrink down to just 7 lines in Spring Boot.

After 6 sessions, you will walk away with a functional portfolio piece: a Todo List REST API built with Spring Boot + JPA.
