Mastering System Design: From Basics to Cracking Interviews | Udemy

System design is a critical skill for software engineers, whether you’re developing real-world applications or preparing for technical interviews at top tech companies. As software systems grow in complexity, engineers must understand how to design architectures that scale efficiently, handle high traffic, and remain resilient to failures. This course takes you on a structured journey, starting from fundamental concepts and progressing to advanced architectural patterns used in industry-leading applications.

Throughout this course, you’ll gain a deep understanding of scalability, availability, reliability, and fault tolerance—key principles that drive modern system design. You’ll explore monolithic vs. microservices architectures, distributed systems, caching mechanisms, load balancing, and database scaling techniques. Each topic is reinforced with real-world case studies, showing how major tech companies design systems like URL shorteners, messaging platforms, and e-commerce applications.

Beyond the technical aspects, this course also focuses on interview preparation, providing structured frameworks for solving system design questions in high-stakes job interviews. You’ll learn how to break down problems, communicate design decisions effectively, and handle trade-offs in scalability, performance, and maintainability. Mock interview scenarios and hands-on exercises will ensure you can confidently tackle system design challenges.

By the end of this course, you’ll be equipped with the knowledge and problem-solving mindset needed to design efficient, scalable, and robust systems. Whether you’re an aspiring software engineer, an experienced developer looking to upskill, or someone preparing for FAANG-level system design interviews, this course will give you the expertise to excel in both real-world projects and technical interviews.
