- Secure user registration and JWT-based authentication.
- Hierarchical product catalog with filtering, searching, and pagination.
- Database-backed shopping cart with strictly isolated user access.
- Checkout system utilizing atomic database transactions to ensure data integrity.
- Asynchronous email notifications for order confirmations via Celery.
I started developing this API with the core database models for products and categories. I used generics to maintain explicit control over HTTP methods and routing. After securing the endpoints with JWT authentication, I implemented the business logic for a database-backed shopping cart. I designed the checkout process using Django’s atomic transactions to ensure safe order creation and proper cart clearing. Finally, I integrated Docker, Redis, and Celery to handle background sending of order confirmation emails without blocking the main API thread.
