What You'll Be Able To Do
After completing this course, you will confidently:
- Build production REST APIs with Spring Boot using layered architecture, validation, and global error handling
- Design and query relational databases with JPA/Hibernate including relationships, caching, and query optimization
- Implement secure authentication and authorization with Spring Security, JWT tokens, and OAuth2
- Build event-driven microservices with Apache Kafka for asynchronous communication and data pipelines
- Design caching strategies with Spring Cache and Redis to optimize API response times
- Write comprehensive test suites with JUnit 5, Mockito, and Testcontainers for integration testing
- Implement reliability patterns including circuit breakers, retries, and rate limiting
- Containerize and deploy Spring Boot applications with Docker and Docker Compose
What You'll Build
Real portfolio projects that showcase your skills to employers.
Multi-Tenant REST API
Build a multi-tenant API with Spring Boot featuring tenant isolation at the database level, JWT authentication, RBAC, pagination, filtering, and comprehensive Swagger documentation.
Interview value:
Multi-tenancy is a complex architecture topic that demonstrates understanding of data isolation, security, and enterprise patterns.
Event-Driven Order Processing Pipeline
Design an order processing system with Kafka event streaming, saga pattern for distributed transactions, dead-letter queues for failure handling, and real-time status tracking.
Interview value:
Event-driven architecture with Kafka is the top-asked topic in senior Java backend interviews at companies like Flipkart, Swiggy, and Walmart.
Distributed Notification Service (Capstone)
Build a notification microservice supporting email, SMS, and push channels with priority queues, template management, delivery tracking, retry logic, and monitoring dashboards.
Interview value:
Notification systems test your understanding of queues, retries, idempotency, and distributed system reliability.

Frequently Asked Questions
Will I get a job after completing this program?
Java backend roles are consistently among the most demanded positions in enterprise software, banking, and e-commerce. Our curriculum covers the Spring Boot, JPA, Kafka, and Docker skills that these employers evaluate. While we cannot guarantee placement, the program produces job-ready engineers.
Do I need experience with Spring Boot or Kafka?
No. We teach every framework from scratch. You need basic Java knowledge (classes, interfaces, collections), but all Spring Boot, JPA, Kafka, and Docker concepts are taught from the ground up.
How is this different from the Java Full-Stack + React course?
This course focuses exclusively on backend engineering — going deeper into Kafka, reliability patterns, microservices, and observability. The full-stack course splits time between backend and React frontend. Choose this if you want to specialize in backend engineering.
Is Kafka really necessary for a junior developer?
Kafka is used in most large-scale systems. Even if your first job does not use Kafka, understanding event-driven architecture makes you a stronger backend engineer and opens doors to better roles faster.
Does this cover microservices?
Yes. Week 13 covers microservices patterns including service decomposition, API gateway, inter-service communication, and the saga pattern. The capstone project is a distributed notification service.
What if I miss a live session?
All sessions are recorded and available on the student portal within 24 hours. The instructor and TAs are available on Slack for questions.
