A backend API for managing products and sellers in an e-commerce platform. Built using FastAPI, SQLAlchemy, and JWT Authentication, this project supports versioned, modular development and can be used as a base for marketplace-style systems.
- Modular folder structure
- JWT-based login and token management
- CRUD operations for Products and Sellers
- PostgreSQL-ready using SQLAlchemy ORM
- Interactive API docs via Swagger & ReDoc
