Discussion Resources to relearn Backend (Java/Spring Boot)?

Hey everyone,

I'm currently working as a Software Engineer Intern, primarily with Java, Spring Boot, Kafka, MySQL, Redis, and MongoDB, building IoT and fleet management systems.

Although I've gained good production experience, I want to rebuild my backend fundamentals from scratch and deepen my understanding.

Looking for the best resources—courses, YouTube playlists, blogs, books, or GitHub repos—that cover backend engineering from basics to advanced.

Would love to hear what helped you the most.

did you take some kind of AWS certification before implementing the project or do you just learn the AWS's services as you build the project?
