Java Backend Development Course

Hours: 144

Lessons per week: 3

Duration: 6 Months

With the Java Back-End Programming Course, you will learn Java from scratch, develop server-side applications and REST APIs using Spring Boot, and gain practical skills in databases, security, microservices, and deployment processes.

The course is designed for individuals who want to build a career as a Java Back-End Developer, expand their knowledge, and prepare for the job market by working on real-world projects.

Who is a Java Back-End Developer?

A Java Back-End Developer is a specialist who develops the server side of web and mobile applications—the part that is not visible to users. They build the application’s business logic, process data, manage databases, create APIs, and ensure that the system operates securely, quickly, and reliably.

Simply put, a Java Back-End Developer is responsible for ensuring that every action performed by a user within an application produces the correct result behind the scenes.

Why is learning Java Back-End programming important?

Modern companies need secure, reliable, and scalable server systems. Java is one of the main technologies widely used in banking, finance, e-commerce, telecommunications, and large-scale corporate projects.

By learning Java Back-End programming, you gain professional skills that are in demand in both local and international job markets.

The main advantages of this field include high demand, strong career growth, competitive salaries, opportunities to work on large-scale projects, the ability to build secure and reliable systems, a wide range of career options across different industries, and access to the global job market.

As your experience grows, your opportunities to work remotely, join international projects, and build a career in global companies will also expand.

What skills will you gain during the Java Back-End Programming Course?

Throughout the course, you will gradually progress from the fundamentals of Java programming to Spring Boot, PostgreSQL, REST APIs, security, microservices architecture, and DevOps processes.

• Java fundamentals: You will learn Java syntax, variables, data types, operators, control structures, loops, and methods to write clean and algorithmic code.

• Object-Oriented Programming (OOP): You will develop structured applications by applying concepts such as classes, objects, encapsulation, inheritance, polymorphism, and abstraction.

• Advanced Java: You will learn to work with Collections, Generics, Exception Handling, Stream API, Lambda expressions, and Multithreading.

• Databases and PostgreSQL: You will learn to write SQL queries, store, filter, and sort data, and manage databases.

• Spring Boot and REST APIs: You will develop server-side applications and REST APIs that enable data exchange between web and mobile platforms.

• JPA and Hibernate: You will connect Java applications to databases, create entity and repository structures, and perform CRUD operations.

• Enterprise security: You will learn to protect user accounts, sessions, and API endpoints using Authentication, Authorization, and JWT.

• Microservices and deployment: You will build distributed systems using Docker, Apache Kafka, and RabbitMQ, and prepare projects for testing and production environments using Git, GitHub, and CI/CD.

How is the course conducted?

The topics are taught progressively, starting with Java fundamentals and moving on to OOP, databases, Spring Boot, security, and microservices. Each topic is reinforced through coding tasks, practical exercises, and real-world projects.

During the course, you will build server-side applications, RESTful APIs, and database-driven projects, allowing you to create your own professional portfolio.

You will receive mentor support to resolve questions and challenges, while also becoming familiar with technologies and teamwork processes used in real companies. After completing your final project, you will have the essential knowledge and practical experience required to begin working as a Java Back-End Developer.
