## Overview

ResumePilot is a web-based resume builder. The visible workflow is account access, resume management, editing resume sections and styling, then viewing a rendered preview. The backend provides authenticated user and resume endpoints backed by models and a database connection. The tree also shows an AI service module, but its behavior and integration are not established by the sampled source. The graph omits the deprecated backend; frontend page-to-service wiring beyond the sampled app bootstrap is not asserted.

Main entry points: [`Backend/src/routes/user.routes.js`](https://github.com/nitya0009/ai-resume-builder/blob/main/Backend/src/routes/user.routes.js) (User routes), [`Backend/src/routes/resume.routes.js`](https://github.com/nitya0009/ai-resume-builder/blob/main/Backend/src/routes/resume.routes.js) (Resume routes), [`Backend/src/app.js`](https://github.com/nitya0009/ai-resume-builder/blob/main/Backend/src/app.js) (Express app), [`Frontend/src/App.jsx`](https://github.com/nitya0009/ai-resume-builder/blob/main/Frontend/src/App.jsx) (App bootstrap)
