Building a Modern Careers Portal with React + FastAPI

I’ve recently started building a complete Careers Portal from scratch, and I thought it would be interesting to document the journey.

Instead of only creating a frontend where users can browse jobs, I wanted to build the complete application flow that companies actually need.

Tech Stack

Frontend

• React
• Vite
• Tailwind CSS

Backend

• FastAPI
• SQLAlchemy
• Alembic
• JWT Authentication

Database

• PostgreSQL

Features I’m Working On

• Dynamic Job Listings
• Job Details Page
• Application Form
• Resume Upload
• Store Applications in PostgreSQL
• Admin APIs
• Authentication
• Download Candidate Resumes
• REST APIs with Swagger Documentation

What I’ve Learned So Far

One thing that became clear very quickly is that building the backend is much more than creating CRUD APIs.

For example, resume uploads require:

• File validation
• Unique filenames
• Secure storage
• Database references
• Proper error handling

I also ran into validation issues while submitting applications, such as sending a string job ID instead of the integer expected by the backend. Fixing these small integration problems helped me understand how important API contracts are between the frontend and backend.

What’s Next

Over the next few days I’ll be implementing:

• Admin Dashboard
• Application Management
• Search & Filters
• Pagination
• Email Notifications
• Production Deployment
• Docker Support

I’ll be sharing what works, what breaks, and what I learn along the way.

If you’re building with FastAPI or React, I’d love to hear how you’re structuring your projects.
