You will get I will build a full-stack web app with React, FastAPI, and PostgreSQL
Project details
You will get a production-ready full-stack web application built with React/Next.js frontend, FastAPI (Python) backend, and PostgreSQL database — deployed and live on day 1.
I have 4+ live apps in production, including an e-commerce store, a contract management system, and a document verification tool. I write clean, documented code and communicate clearly throughout the project.
What makes my work different:
• I deliver working software at every stage, not just at the end
• You get a staging URL to review progress before final delivery
• Full source code + deployment included in every package
• I explain what I built so your team can maintain it
Starter ($200): Simple CRUD app with auth — perfect for MVPs and internal tools
Standard ($400): Full web app with admin panel, custom features, and API documentation
Advanced ($750): Complex app with AI integration, payment gateway, and n8n automation
