I will build a production ready python backend API
Vitaly Sem
About this gig
Need a reliable Python backend or API built for real production use not just a quick prototype?
I build and extend production-ready backend systems using Python, Django, Django REST Framework, and FastAPI.
I can help with:
REST API development
Backend modules and business logic
PostgreSQL / MySQL integration
Authentication, JWT, roles, and permissions
Third-party API integrations
Redis, Celery, and background jobs
Error handling and validation
Automated tests
OpenAPI / Swagger documentation
Docker-ready backend setup
My focus is clean architecture, maintainable code, predictable behavior, and reliable integration with your existing system.
This gig is ideal for focused API features, complete backend modules, and production-ready backend components.
Large applications, complete SaaS backends, complex integrations, and multi-service architectures require a custom offer.
Please contact me before ordering if the scope is large or unclear.
