E-Commerce App with Payment using FastAPI & React

Build  a complete, production-grade e-commerce application from scratch using FastAPI for the backend and React for the frontend. This project-driven course is designed to take you far beyond basic CRUD operations, teaching you how to architect, secure, automate, and deploy a robust enterprise platform from the ground up.

On the backend, you will build a high-performance asynchronous API using modern Python standards, FastAPI, SQLAlchemy, and Alembic database migrations with support for both PostgreSQL (asyncpg) and MySQL (asyncmy). Security and identity management are core focal points of this course: you will implement secure authentication utilizing PyJWT, Argon2 password hashing via passlib and pwdlib, Google OAuth2 single sign-on using Authlib, and fine-grained Role-Based Access Control (RBAC) to isolate permissions across distinct Customer, Admin, and Delivery personnel workflows.

Furthermore, you will integrate real-world third-party services to handle high-value operational tasks. You will connect the Stripe API for processing online checkout payments securely, utilize Jinja2 to build dynamic custom HTML email templates, and automate transactional messaging using asynchronous email transport (aiosmtplib). For media storage, you will leverage Amazon Web Services via boto3 to manage product uploads effortlessly.

On the frontend, you will develop a responsive, component-driven application in React. You will leverage modern React patterns, modern state management, and client-side router guards for strict route protection based on user roles. You'll establish dedicated operational interfaces for customers to browse products and manage carts, admins to manage inventory and user roles, and delivery agents to track and fulfill orders in real time.

Finally, you will bridge the gap between development and production. You will craft complete CI/CD pipelines, build automated deployment and validation scripts, run integration tests using httpx, and ensure your full-stack environment is fully prepared for continuous delivery and enterprise stability.
