FAQs

Frequently Asked Questions

Yes. Programming and Core Java begin from fundamentals.

Yes. It omits the deep frontend curriculum and uses that time for substantially deeper backend engineering, concurrency, JVM, databases, transactions, security, distributed systems, performance and system design.

Modern Java with Java 17, 21 and 25-era development as the primary baseline, plus legacy Java 8/11 awareness.

Yes. The curriculum is designed for the current stable Spring Boot generation and includes Spring Boot 3 and Jakarta migration awareness.

Yes. SQL, PostgreSQL, JDBC, JPA, Hibernate, migrations, transactions, locking and database performance are covered.

Yes. The course covers Spring Security, JWT, OAuth2/OIDC, RBAC, method authorization and API security.

Yes. They are core production-backend topics, including event-driven workflows, idempotency, Saga, outbox and resiliency.

Yes. The deployment path includes Docker, Kubernetes, AWS and CI/CD.

Yes. JVM diagnostics, garbage collection, concurrency, virtual threads, profiling and performance engineering receive dedicated coverage.

Yes. Design patterns, LLD, backend system design, architecture cases and production troubleshooting are included.

Yes, as a dedicated interview-preparation track alongside Java coding, SQL, JVM, Spring and system design.

Yes, as an advanced module with explicit guidance on when reactive architecture is appropriate.

AI integration and Spring AI awareness are included as modern backend competencies without replacing core backend engineering.

No. The program provides Placement Assistance & Career Support; employment depends on learner performance, portfolio, experience and employer requirements.
