You’ll learn both Low Level Design (LLD) and High Level Design (HLD) through a structured and practical learning path. Starting with object-oriented design principles, SOLID principles, design patterns, UML, class design, and clean architecture, you’ll learn how to convert requirements into well-structured and maintainable code.

As you progress, the course moves into Advanced High Level System Design, covering scalable architectures, microservices, distributed systems, databases, API design, caching, message queues, load balancing, replication, sharding, fault tolerance, consistency, availability, and performance optimization.

You’ll also understand how popular systems and real-world applications can be designed at scale. Through practical system design problems, you’ll learn how to identify requirements, estimate capacity, choose the right technologies, define system components, design data flow, handle millions of users, and make meaningful architecture trade-offs.

The course focuses not only on what to design, but also on why a particular design decision should be made. You’ll learn how to evaluate different architectural approaches based on scalability, performance, reliability, maintainability, cost, and complexity.

For Low Level Design, you’ll work with practical examples involving OOP, SOLID principles, interfaces, abstraction, inheritance, composition, design patterns, extensible class structures, and clean code. You’ll learn how to design systems such as parking lots, libraries, vending machines, notification systems, payment systems, elevators, and other commonly asked LLD problems.

For High Level Design, you’ll explore real-world architecture concepts including monoliths, microservices, REST APIs, databases, Redis, caching, Kafka, message queues, load balancers, CDNs, horizontal scaling, database replication, sharding, CAP theorem, consistency models, fault tolerance, and distributed system design.

You’ll also get exposure to system design case studies such as designing a URL shortener, social media platform, chat application, food delivery system, ride-sharing platform, video streaming platform, notification system, e-commerce platform, and other large-scale applications.

Whether you’re preparing for Software Engineer, Backend Engineer, Senior Software Engineer, SDE II, SDE III, or Staff-level interviews, or simply want to understand how production-grade applications are architected, this course provides a structured path from fundamental design concepts to advanced distributed system architecture.

By the end of the course, you’ll be able to approach complex system design problems systematically, communicate your architectural decisions clearly, identify bottlenecks, design for scale and reliability, and build solutions that are easier to maintain and evolve.

Join us and build the system design skills needed to move from simply writing code to designing complete, scalable, and production-ready software systems.
