About this gig

Are you building an ecommerce app and need a solid backend API? I'll build you a production-ready REST API using FastAPI and Python.


What you get:

  • JWT authentication with access & refresh tokens
  • Role-Based Access Control (Admin / Seller / Buyer)
  • Products, Categories, Orders & Cart endpoints
  • PostgreSQL database with async SQLAlchemy
  • Redis for caching, sessions & rate limiting
  • Background email notifications via Celery
  • Full Docker setup runs with one command
  • Auto-generated Swagger & ReDoc API docs
  • Clean, well-structured code with Alembic migrations


Why choose me?

  • Async FastAPI fast and scalable
  • Secure by default (JWT blacklisting, input sanitization, CORS)
  • Dockerised with Nginx ready for production
  • Tests included (pytest + fakeredis)
  • Prometheus metrics & structured logging


I deliver clean, maintainable code with full source code and documentation.


Feel free to message me before ordering to discuss your requirements!
