I will develop a python backend rest API and third party integrations


About this gig
Need a backend feature, REST API, or third-party integration that fits your existing application?
I develop practical Python backend services for web and mobile applications. My primary stack is FastAPI and PostgreSQL, and I can also review compatible Django, Flask, SQLAlchemy, REST API, and existing codebase requirements before confirming the scope.
I can help with:
- REST API endpoints and business logic
- PostgreSQL models and database queries
- Authentication and role-based access
- Third-party API and webhook integrations
- Request validation and structured error handling
- Existing API debugging and improvements
- API documentation and deployment support
I first review the required workflow, existing stack, expected requests and responses, and external dependencies. This helps us agree on a clear deliverable rather than beginning with an unclear scope.
Please message me before ordering if your project involves an existing production system, multiple integrations, background workers, or a custom architecture.
Third-party subscriptions, hosting, API usage charges, and paid services are not included.

FAQ
Can you work on an existing backend?
Yes. Share the current stack, repository structure, issue, expected behavior, and relevant documentation so I can review compatibility first.
Can you use Django or Flask instead of FastAPI?
Possibly. FastAPI is my primary backend framework, but I can work with compatible Python projects after reviewing the requirements.
Does the package include deployment?
Basic deployment assistance can be added after reviewing the hosting platform. Infrastructure setup, migrations, and production configuration may require a custom offer.
What counts as a revision?
A revision corrects delivered work according to the agreed requirements. New endpoints, workflows, integrations, or changed requirements are additional scope.
