About this course

Level up from coder to Java backend developer. This intermediate program from Ucanly takes practitioners with working knowledge of core Java, OOP, collections, exceptions, JDBC, and Git into professional backend engineering: advanced Java features like records and pattern matching, concurrency with virtual threads and CompletableFuture, and the Spring Framework with dependency injection and Spring Boot auto configuration. You will build data persistence layers with JPA, Hibernate, and Flyway migrations, and in your minor project in week five, build a production grade REST API with Spring Boot and Spring Data JPA, JWT security, validation, migrations, a full test suite, and Docker packaging. You will master Spring Security, professional testing with JUnit, Mockito, and Testcontainers, and move into performance and AI engineering with Redis caching, async processing, and RAG powered features using Spring AI. You will graduate having built a complete enterprise backend in your week ten major project, with caching, async processing, a RAG powered AI layer, CI/CD, containerized deployment, and API documentation, running live. This course contains 8 modules and 47 lessons in total, matching the full course structure exactly.
