## Overview

This repository is a backend-development learning collection, not a single deployed application. Its learner-facing path moves from backend fundamentals through Node.js concepts and practice to Express routing practice; the README also documents broader study areas, including APIs, authentication, databases, security, deployment, and interview preparation. The graph preserves those documented branches, but several have no corresponding files in the supplied tree. Relationships among those branches are therefore limited to the README’s learning-module outline; no unsampled implementation flow is inferred.

Main entry points: [`Readme.md`](https://github.com/beautymauryaa/backend-dev/blob/main/Readme.md) (Learning roadmap), [`NodeJS`](https://github.com/beautymauryaa/backend-dev/tree/main/NodeJS) (Node.js concepts), [`express-server/practice/server.js`](https://github.com/beautymauryaa/backend-dev/blob/main/express-server/practice/server.js) (Express route practice), [`01-backend-fundamentals`](https://github.com/beautymauryaa/backend-dev/tree/main/01-backend-fundamentals) (Backend fundamentals)
