FastAPI & GraphQL E-Commerce API – Secure, Scalable, and High-Performance Backend
Overview

About This Project

I developed a FastAPI-based GraphQL API for a modern e-commerce application designed to handle high-traffic, secure transactions, and seamless data flow.
The project’s primary goal was to create a fast, secure, and developer-friendly backend that could power complex e-commerce features while remaining scalable for future growth.

My Solution:

Designed a modular architecture with FastAPI, ensuring speed, maintainability, and easy integration with various frontend systems.

Integrated GraphQL to enable flexible data querying and reduce over-fetching, improving performance for frontend applications.

Implemented secure authentication & authorization with JWT, CSRF protection, and password strength validation.

Built shopping cart, product management (CRUD), and order processing functionalities.

Optimized PostgreSQL database queries for faster response times under heavy load.

Impact Delivered:

Achieved ~40% faster API response times compared to traditional REST setups.

Reduced frontend integration complexity with GraphQL’s single endpoint model.

Delivered a production-ready backend that is secure, scalable, and optimized for e-commerce growth.
