Master System Design, HLD & LLD with real-world case studies, design patterns, and interview preparation

What you'll learn
- Design scalable and fault-tolerant systems that can handle millions of users like Netflix, Instagram, and Uber.
- Understand and apply core system design concepts such as caching, load balancing, database sharding, replication, and API gateways.
- Master both High-Level Design (HLD) and Low-Level Design (LLD) with real-world case studies and hands-on design exercises.
- Use design patterns and SOLID principles to write clean, extensible, and maintainable software architectures.
- Analyze trade-offs and make architectural decisions for distributed systems focusing on performance, availability, and scalability.
- Crack system design interviews confidently with structured frameworks, estimation techniques, and mock interview examples.
- Model real-world projects from scratch, including chat apps, e-commerce systems, video streaming platforms, and payment systems.

Requirements
- A computer with internet access for watching lectures, drawing diagrams, and completing assignments
- Basic understanding of programming in any language (Java, Python, jаvascript, etc.)
- Familiarity with web applications — knowing how APIs or databases work is helpful but not mandatory
- Curiosity to learn how large-scale systems work — from login systems to global apps like Netflix or WhatsApp
- No prior experience in system design is required — this course starts from the fundamentals and builds up to advanced topics

Description
Are you preparing forSystem Design interviewsor aiming to understand how large-scale applications likeNetflix, Instagram, Uber, and WhatsAppare built and scaled?ThisSystem Design Masterclass 2025is a complete, step-by-step course that helps you masterHigh-Level Design (HLD),Low-Level Design (LLD), andreal-world architecture principlesfrom scratch — even if you're a beginner.

You'll start withfundamentalssuch as scalability, reliability, availability, consistency, and fault tolerance. Then, you'll dive deep intocore componentslike caching, databases, sharding, replication, load balancing, and message queues. Every concept is taught visually with real-world analogies and diagrams to ensure you understandhow and whysystems work.

Once the foundations are clear, we'll designreal-world systemssuch as URL Shorteners, YouTube, Twitter, Zomato, Uber, and Payment Systems — exploring design choices, trade-offs, and performance optimization techniques. You'll also learnLow-Level Design (LLD)andDesign Patternslike Singleton, Factory, Observer, and Strategy using practical examples and code-level thinking.

By the end of this course, you will:

Design scalable, high-performance distributed systems

Understand and apply key architectural trade-offs

Build clean and extensible LLDs using OOP and SOLID principles

ApproachSystem Design Interviewswith confidence and structure

Whether you are astudent,software developer, orengineer preparing for FAANG or top MNC interviews, this course will guide you to think, design, and communicate like a system architect.
