## Overview

DevTinder is a developer-connection social platform. Its main user journey is account access and profile setup, discovering developers, sending and reviewing connection requests, then chatting with accepted connections; premium purchase is a separate monetization path. The graph also includes documented email, scheduling, and media capabilities. Backend route and integration links are grounded in sampled route code or README claims; unsampled frontend API wiring and background-job internals are not inferred.

Main entry points: [`Frontend/src/App.jsx`](https://github.com/iambuzzz/devtinder/blob/main/Frontend/src/App.jsx) (App routes), [`Backend/src/models/user.js`](https://github.com/iambuzzz/devtinder/blob/main/Backend/src/models/user.js) (User records), [`Backend/src/middlewares/auth.js`](https://github.com/iambuzzz/devtinder/blob/main/Backend/src/middlewares/auth.js) (JWT authorization), [`Backend/src/routes/profileRouter.js`](https://github.com/iambuzzz/devtinder/blob/main/Backend/src/routes/profileRouter.js) (Profile management)
