FastAPI Backend Server

This repository contains a FastAPI backend server that powers a job-matching system. It handles resume parsing, user and employer creation, and job posting automation using parsed job descriptions. The application leverages MongoDB for data storage, PyPDF2 for PDF parsing, and Clerk for authentication and user management.

▶️ Running the Server

Run the development server using Uvicorn:

uvicorn app.main:app --reload

The server will start at: http://localhost:8000

---

📤 Resume Upload Flow

1. User uploads a resume (PDF format) to the /upload-resume endpoint.
2. The PDF is parsed using PyPDF2 to extract relevant user and employer information.
3. A new user is created automatically using Clerk.
4. An associated employer profile is created and stored in MongoDB.
5. Resume files are stored in the public/ folder.

---

📝 Job Description Upload Flow

1. A job description file is uploaded or job details are submitted via API.
2. Job details are parsed to extract structured information.
3. A new job entry is created and stored in MongoDB.

---

🔗 API Endpoints (Examples)

These are sample routes; actual routes may differ based on implementation:

Method	Endpoint	Description
POST	/upload-resume	Upload resume and create user
POST	/upload-job-description	Upload job description and create job
GET	/jobs	List all available jobs
GET	/users/{user_id}	Retrieve user details

For complete API reference, see /docs (FastAPI's built-in Swagger UI).
