This module introduces the fundamentals of system design, explaining the importance of scalable architecture in modern applications. You’ll learn the basics of High-Level Design (HLD) and Low-Level Design (LLD), understanding how to approach system problems logically and structure your solutions for interviews.

Learn about the essential building blocks of scalable systems, including Load Balancers, Caching, Message Queues, and Database Sharding. This module teaches how these components interact to handle traffic efficiently and improve performance in real-world applications.

Apply your learning to practical examples like URL Shortener, Chat App, Instagram Feed System, and Google Docs Collaborative System. You’ll analyze real-world systems, learn design trade-offs, and see how scalable architectures are implemented in production.

Learn to design RESTful APIs, understand API Gateway concepts, and explore microservice architecture. This module focuses on building modular, maintainable backend systems that can scale to meet enterprise requirements.

Master creating professional architecture diagrams and learn key scalability principles. This module teaches how to visualize systems clearly, justify design choices, and communicate your solutions effectively in interviews.

Prepare for technical interviews with mock system design rounds, solution structuring, and scenario-based exercises. Learn how to explain your design decisions confidently, optimize systems, and highlight your skills to FAANG and startup recruiters.

Work on hands-on system design projects to consolidate your learning. Build a small-scale, end-to-end system and document it in a GitHub portfolio, giving you a professional edge in interviews and resumes.
