Description
AI Usage Disclosure
“This course contains the use of artificial intelligence.”
Welcome to this course on building a real world online banking system using microservices.
In this course, we focus on the core banking capabilities that almost every bank depends on. These capabilities are designed and implemented the same way they are built in real production systems.
What this course is about
This course does not attempt to build everything.
Instead, it deliberately focuses on a small but realistic functional scope and uses that scope to go deep into real world system design.
You will learn how banking domains are modeled using Domain Driven Design and how responsibilities are split across independent microservices.
The course also explains how real production systems handle security and authentication, data ownership and service boundaries, asynchronous processing and reliability, as well as scalability and failure scenarios.
Every architectural decision in this course is based on real industry experience building and operating large-scale banking and fintech platforms.
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.
Who this course is for:
- Backend developers and software engineers who want to understand how real-world digital banking systems are designed and built using microservices.
- Java and Spring Boot developers looking to move beyond CRUD applications and learn production-grade system design and architecture.
- Engineers interested in fintech and payments, who want to see how concepts like accounts, transactions, and payments work in real banking systems.
- Developers transitioning into microservices or distributed systems, seeking practical, applied examples instead of abstract theory.
- Senior developers and architects who want to understand domain-driven design and event-driven workflows in a realistic banking context.
