How do you assess your experience with Spring Boot? How deeply have you had to understand how it works under the hood?

My experience with Spring Boot includes creating REST APIs, configuring settings, and integrating with databases. I am familiar with the main annotations and principles of the framework.

I haven't delved deeply into the internal workings of Spring Boot yet, but I understand that it is based on the Spring Framework and uses auto-configuration, inversion of control, and dependency injection to simplify development. I plan to study its internal mechanisms, such as context loading, bean processing, and application lifecycle, in the future.
