🧠 System Design Lab v5.0.0 — Full Platform Release

Live at: https://sumit6258.github.io/System-Design/

The most comprehensive interactive system design learning platform on the web.
No setup. No login. No framework. Just open and learn.

🚀 What's Inside

25 fully interactive sections covering everything from OOP basics
to distributed systems — all in a single file.

🎓 Learning & Curriculum

  • Structured 4-track Learning Path (Beginner → Intermediate → Advanced → Expert)
  • 24 modules with subtopics, time estimates, outcomes, and quiz questions
  • Covers OOP → SOLID → GoF Patterns → HLD → Distributed Systems → Staff-level design
  • Progress tracking per track with stats bar

💻 Low-Level Design (LLD)

  • OOP deep-dives: Encapsulation, Abstraction, Inheritance, Polymorphism
  • All 5 SOLID principles with violation → fix code comparisons
  • All 23 GoF Design Patterns (Creational, Structural, Behavioral) with code + diagrams
  • UML class relationships, sequence diagrams, use case diagrams

🏛️ High-Level Design (HLD)

  • Architecture patterns: Monolith, Microservices, Event-Driven, CQRS, Hexagonal
  • Scalability deep-dive + Non-Functional Requirements (NFRs)
  • CAP Theorem with interactive triangle and real database positioning
  • Infrastructure: Load Balancers, Caching, CDN, Message Queues, Circuit Breaker

⚡ Live Simulations & Labs

  • Real-Time Traffic Simulator — 100 RPS to 10M RPS with bottleneck detection
  • Chaos Engineering Lab — inject failures, apply mitigations, track resilience score
  • CAP Theorem Playground — simulate network partitions across 6 real databases
  • Global Traffic Map — canvas-based world map with 14 AWS regions, CDN routing,
    region failover, latency heatmap, and live traffic flow modes

🛠️ Tools & Builders

  • Drag-and-drop Architecture Builder with AI Advisor
  • Excalidraw-style Whiteboard with component stamps and PNG export
  • AI Architecture Generator for 8 major systems (YouTube, WhatsApp, Uber, etc.)
  • System Design Playground — step-by-step walkthroughs for 5 real systems
  • 3D Architecture Lab powered by Three.js

🎯 Interview Preparation

  • Mock Interview Coach — 3 difficulty tiers (Junior / Senior / Staff), countdown timer,
    per-question FAANG checklists, and Strong Hire / Hire / Borderline / No Hire scoring
  • 8 FAANG Question Bank with animated solutions and architecture diagrams
  • 7-step Interview Wizard with guided prompts and evaluation rubric
  • Distributed Systems Survival Game

📊 Analytics & Estimation

  • Latency Heatmap with interactive parameter sliders
  • Scalability Analysis with animated comparisons
  • Infrastructure Cost Estimator — 6 inputs → 8 AWS cost line items with doughnut chart
  • Capacity Calculator

🔒 Security

  • Source code obfuscated and watermarked
  • SHA-256 authorship fingerprint embedded
