🧠 Backend System Design Concepts by Siddhant Kadam

Welcome! This repository contains core backend development patterns, real-time architecture, and practical Go/Node.js concepts that I've learned and implemented — explained in a simplified and reusable way.

🚫 Note: This repo contains only generic concepts and no private or business-specific code.
Everything here is structured to help others (and myself) learn and re-use patterns safely.

📌 Why This Repo Exists

While working on real-time systems and scalable microservices, I encountered many reusable ideas and architectural patterns.
This repo acts as a public knowledge base, allowing me to:

• Document learnings cleanly
• Help others facing similar backend challenges
• Keep production code private while still showing my expertise
