🏗 Backend Engineering Mastery — From Core Java to Spring Boot

---

📖 Overview

This project is a comprehensive, hands-on backend engineering curriculum designed to take you from Java fundamentals to building production-ready APIs with Spring Boot — the way professional backend engineers work.

It’s split into modules that follow a logical learning path.
Each module contains:

1. 📚 Topic Readme — Explains key concepts in a clear, concise way
2. 🔁 Repeat-Style Assignments — Short, focused exercises to master the concept
3. 📦 Mini Project — A small, real-world-style implementation
4. 🏁 Capstone — A larger, combined project at the end of the module

As time goes on, more modules will be added to cover advanced topics such as Spring Security, Microservices, Databases, Cloud Deployments, and more.

By the end of this repository, you’ll be able to design, build, test, and deliver backend applications that follow professional standards.
