System Design

👋 Welcome to my System Design repository!

This repository is designed to help both myself and others learn and understand the principles of system design. It will cover a wide range of topics as I progress through my learning journey.

🌟 What makes this repository unique?

I aim to explain each concept in a way that is easy to understand – as if I’m explaining it to a friend. You will find:

✅ Real-world examples and practical applications
✅ Code snippets and implementations wherever relevant
✅ Clear explanations focusing on why something is designed a certain way, not just how
