Program Description
This course is built around modern Java and backend engineering with Spring Boot. You’ll start with language fundamentals (streams and lambdas, concurrency with CompletableFuture, error handling, generics, annotations) and core JVM internals (memory model, garbage collection, multithreading). Then you’ll move into backend essentials—building RESTful services with Spring Boot, adding validation, authentication (Spring Security, JWT), API security, and testing with JUnit. You’ll design schemas and write efficient SQL with PostgreSQL/MySQL, leverage ORMs like Hibernate or JPA, and apply caching and messaging (Redis, Kafka). Next, you’ll containerize with Docker, set up CI/CD pipelines in GitHub Actions or Jenkins, and deploy services to AWS with observability (logging, metrics, tracing).
