## Overview

This repository implements a recruiting platform backend for candidate and recruiter accounts, job listings, applications, profiles, and posts, with a small Next.js frontend whose sampled files expose a login form. The backend workflow is HTTP routing through authentication and feature controllers to PostgreSQL-backed models; application and post actions can also upload files to ImageKit. The README is empty, so capabilities are inferred from the source index and sampled files. Frontend-to-backend wiring and several unsampled feature details are not established by the available evidence.

Main entry points: [`Backend/src/app.ts`](https://github.com/mustbesarthak/hireflow/blob/main/Backend/src/app.ts) (HTTP application), [`Backend/src/config/db.ts`](https://github.com/mustbesarthak/hireflow/blob/main/Backend/src/config/db.ts) (PostgreSQL), [`Backend/src/routes/jobs.routes.ts`](https://github.com/mustbesarthak/hireflow/blob/main/Backend/src/routes/jobs.routes.ts) (Job routes), [`Backend/src/routes/applications.routes.ts`](https://github.com/mustbesarthak/hireflow/blob/main/Backend/src/routes/applications.routes.ts) (Application routes)
