The first phase focuses on building a solid foundation in programming principles and tools. Learners begin by understanding the JVM, JDK, and basic Java syntax. They then progress to version control using Git, learning how to manage code repositories and collaborate effectively. They then progress to version control using Git,

Using Docker to package applications with all their dependencies.

Backend engineers spend a massive portion of their careers managing application data layers. Backend Developer Roadmap 2025 - GeeksforGeeks Mastering Object-Oriented Programming (OOPs)
