Course Overview
Master Microservices Architecture with Spring Security, Kafka, Event-Driven Design, and Production-Ready Patterns
AI Usage Disclosure
“This course contains the use of artificial intelligence.”
Welcome to the ultimate guide for building a real-world Online Banking System using Spring Boot Microservices.
In this course, we move beyond basic CRUD tutorials to focus on high-concurrency, mission-critical banking capabilities. You will learn to build systems exactly as they exist in modern fintech and tier-1 banks.
Why this course is essential for your career:
Full Tech Stack: We leverage Spring Boot 3, Auth0, Kafka, and PostgreSQL to solve real-world payment challenges.
Architecture First: This isn't just about code. It’s about System Design, Microservices Orchestration, and Cloud-Native patterns.
Production Standards: Learn how to handle Distributed Transactions, Idempotency in payments, and API security.
What makes this course different
Most online courses focus on building features quickly, skipping hard architectural decisions, and avoiding real world constraints.
This course takes the opposite approach.
You will learn why a particular design is chosen, what trade-offs come with each decision, and what breaks in production when those trade offs are ignored.
The goal is to help you understand how engineers think inside real banks, not just how to write working code.
How this course is structured
Before writing any code, we define a clear Functional MVP.
This includes identifying the exact user journeys we are going to support, the exact services involved, and what we are intentionally not building.
This Functional MVP acts as the foundation for the entire course.
Every API, database design, Kafka event, and security decision is traced back to this foundation to ensure architectural consistency.
Who this course is for
This course is designed for backend engineers who want to move beyond CRUD based tutorials, developers curious about real world banking architecture, engineers preparing for senior, lead, or architect roles, and anyone who wants to understand how production-grade systems are actually designed and operated.

It is a very good course for financial systems. However, we would appreciate it if you could share all parts of the code on GitHub. It would also be beneficial to include the implementation of Spring Gateway , eurka discovery , CI/CD and JUnit testing. The approach you are using is quite advanced, and having access to the complete codebase would greatly help in understanding and applying the concepts.

The course offers a clear and practical introduction to building microservices using the Spring ecosystem. The lessons are well-structured with hands-on examples on customer onboarding , account management , transactions and Bill Payments . Highly recommended to anyone who wishes to gain technical depth and functional knowhow in banking domain .
