Back-end Development with JAVA

Build Scalable, Secure, and High-Performance Applications

About the Course

If you are looking to truly master backend development and apply it in real-world projects, this course is for you. Backend Development with Java is your step-by-step guide to becoming a confident backend developer. Whether you are building RESTful APIs, working with databases, or creating scalable web applications – this course has you covered.

We will start with the basics of Java and quickly move to advanced  topics like Spring Boot, Hibernate, and microservices architecture. Along the way, you will learn to build secure, efficient, and production-ready backend systems. You will also work with modern tools like Postman, and Git to streamline your development workflow.

This course includes three real-world projects: a Student Notes Application, an E-commerce Backend, and a Microservices-based Banking System. By the end of the course, you will not only be comfortable using Java for backend development but also have the confidence to apply it to real-world challenges – whether it’s building APIs, or integrating with databases.

This course is designed for anyone ready to get serious about Java backend development – whether you are just starting out or looking to expand your skills. Let’s take your backend development skills to the next level.

What You Will Build / Projects

1. Student Notes Application

In this project, you will build a RESTful API for a student notes application. Students can store, retrieve, update, and delete their notes. You will use Spring Boot, MySQL Database, and Spring Data JPA to create a fully functional backend system.

2. E-commerce Backend

Together, we will develop the backend for an e-commerce platform. You will implement features like product management, order processing, and user authentication. This project will teach you to work with MySQL, Spring Security, and RESTful APIs.

3. Microservices-based Banking System

In this advanced project, you will build a banking system using microservices architecture. You will create separate services for user management, transactions, and notifications.
