System Design Masterory

🚀 System Design Mastery

🎯 Overview

A practical, interview-focused system design course designed to help you master both High-Level Design (HLD) and Low-Level Design (LLD) through real-world system breakdowns and hands-on design practice.

This program is built for software engineers preparing for product-based company interviews, focusing on how large-scale systems are designed, optimized, and structured in real-world engineering environments.

📦 Course Structure

🏗️ 1. High-Level Design (HLD) – 8 Classes

Focus Areas:

  • System design thinking
  • Scalability and distributed systems
  • Real-world architecture design

Concepts Covered:

  • Requirement gathering & clarification
  • Consistency, availability, partition tolerance and trade-offs (CAP theorem)
  • CDN, DNS, API Gateway, Load balancing & caching strategies
  • Authentication and security tradeoffs
  • Networking and network protocols
  • Database selection & sharding
  • Microservices, monolith & service discovery
  • Observability (SLI/SLO/ SLA)
  • Designing scalable architectures

💡 System Design Case Studies:

You will learn how to design and deeply understand:

  • 🔗 TinyURL – URL shortening system
  • 💬 WhatsApp – real-time messaging system
  • 📸 Instagram – feed, media storage, and scaling
  • 🚗 Uber – ride matching & real-time location tracking
  • 📍 Nearby system – location-based services
  • ☁️ Google Drive – file storage and sync system
  • 🎬 Netflix – video streaming architecture
  • 🐦 Twitter (X) – timeline, feed generation, scaling challenges

👉 Goal: Build strong intuition for designing large-scale distributed systems

⚙️ 2. Low-Level Design (LLD) – 4 Classes

Focus Areas:

  • Object-oriented design in real systems
  • Writing scalable and maintainable code structure

Concepts Covered:

  • SOLID principles
  • Design patterns (Singleton, Factory, Strategy, Iterator, Observer, State, Chain of responsibility, Observer etc)
  • Class diagrams & relationships
  • Clean architecture principles
  • Extensible system design

💡 LLD Case Studies:

You will design and structure:

  • 🅿️ Parking Lot System – slots, vehicles, allocation logic
  • 🚗 ZoomCar / Car Rental System – booking, availability, pricing
  • 🎟️ BookMyShow – seat booking & concurrency handling
  • 🏧 ATM System – transactions, security, cash withdrawal flow
  • 🥤 Vending Machine – state management & product selection
  • 🛗 Elevator System – scheduling & request optimization

👉 Goal: Learn how to convert real-world problems into clean object-oriented designs

📊 Key Highlights

  • ✅ 12 structured live classes (HLD + LLD)
  • ✅ Real-world system breakdowns
  • ✅ Interview-oriented design approach
  • ✅ Step-by-step architecture thinking
  • ✅ Focus on trade-offs and scalability decisions

🎯 Who This Course Is For

  • Software engineers preparing for product-based interviews
  • Backend developers targeting system design rounds
  • Developers transitioning from coding to architecture roles
  • Anyone aiming to crack mid/senior-level tech interviews

🗓️ Format

  • Live interactive sessions
  • Whiteboard-based system design explanation
  • Step-by-step problem solving
  • Q&A + interview simulation style learning

💡 Outcome

By the end of this course, you will be able to:

  • Confidently design large-scale systems
  • Break down complex requirements into architectures
  • Write clean low-level designs using OOP principles
  • Handle system design interview questions with clarity
