Build, Architect & Scale Real-World Systems — Hands-On with Code
Welcome to the most practical backend engineering course on the internet — not just theory, but code, real systems, and decisions that scale.
This course is crafted for developers who want to move beyond "CRUD APIs" and start building production-ready, distributed backend systems using Node.js + TypeScript, with a deep dive into Microservices, consistency, patterns, architectural designs, Kafka, Docker, Redis, AWS, and more.
Before starting this course, you should have:
Event-Driven Architecture (EDA) is a design pattern where system components communicate by emitting and listening to events. It helps build decoupled, scalable, and responsive systems, enabling real-time processing and asynchronous communication between services.
CQRS separates the data modification (Command) and data retrieval (Query) logic into different models, optimizing for performance, scalability, and security. It allows systems to handle high-load read and write operations independently, especially in distributed systems.
The Saga Pattern is used for managing long-running transactions and ensuring data consistency across microservices. It breaks down a large transaction into a series of smaller, isolated steps, with compensation actions to handle failures and rollbacks.
Eventual Consistency is a consistency model in distributed systems that allows for temporary inconsistencies between nodes or services. Over time, data will be reconciled to achieve consistency, which is ideal for highly scalable and available systems like e-commerce or social networks.
