Deep Dive: GeeksforGeeks Java Backend Development (UPD – Upgraded Curriculum)

Issued by GeeksforGeeks upon successful completion of all modules and projects.

To become a proficient Java backend developer, follow this structured path: Master Core Java : Focus on fundamental syntax, Object-Oriented Programming (OOPs) geeksforgeeks java backend development upd

• Core Java and JVM internals relevant to backend performance (memory model, GC tuning, class loading).
• Frameworks: in-depth guides on Spring Boot (REST APIs, Spring Data JPA, security with Spring Security, configuration), Jakarta EE basics, and lightweight alternatives (Micronaut, Quarkus).
• Data access: JDBC best practices, ORM usage with Hibernate, transaction management, and query tuning.
• API design: RESTful principles, versioning strategies, error handling, DTO mapping, and OpenAPI/Swagger integration.
• Testing: unit, integration, and contract testing with JUnit, Mockito, Testcontainers, and embedded databases.
• Concurrency & reactive: multithreading patterns, CompletableFuture, Executors, and reactive paradigms with Project Reactor and Spring WebFlux.
• Security: authentication/authorization flows (JWT, OAuth2), input validation, secure configuration, and common vulnerabilities (OWASP Top Ten).
• Performance & observability: profiling, benchmarking, logging best practices, metrics (Micrometer), distributed tracing (OpenTelemetry), and caching strategies (Redis, Caffeine).
• CI/CD & DevOps: containerization (Docker), orchestration basics (Kubernetes), build pipelines (Maven/Gradle), and deployment patterns (blue/green, canary).
• Cloud integration: connecting to managed databases, secrets management, and serverless options for Java backends.
• Project-based tutorials: end-to-end sample projects demonstrating design, implementation, testing, and deployment.
