I will build python backend rest apis with fastapi, flask or django


About this gig
Need a Python backend for your web app, mobile app or internal tool? I will build REST APIs with FastAPI, Flask or Django, with clear request validation and documentation your team can use.
I am a backend engineer with 6 years of experience building production systems using Python, PostgreSQL, Redis and AWS. See my portfolio for examples of API, database and data-access work.
Choose a defined starting point:
Basic: 1 simple endpoint, validation, a focused test and setup guide; no database.
Standard: up to 5 endpoints, 3 database models and JWT authentication.
Premium: up to 10 endpoints, 5 models, role-based access, Docker and 1 deployment.
Every package includes source code, API documentation, setup instructions and focused tests for the agreed behaviour. I confirm endpoints and acceptance criteria before building, then walk you through the handover.
Message me with your workflow, data and required endpoints before ordering. Frontend UI, hosting fees, paid APIs, large migrations and ongoing support require separate scope. One endpoint means one HTTP method + route.

FAQ
What counts as one API endpoint?
One HTTP method plus one route, such as GET /items. GET /items and POST /items count as two endpoints. We agree request/response examples, business rules, database models and acceptance checks before the order.
Which Python framework and database do you use?
I work with FastAPI, Flask and Django. For a new REST API I can use FastAPI; existing projects can keep their framework. Standard and Premium include one PostgreSQL database within the model limits. Other databases or complex integrations need review first.
What is included in the $50 Basic package?
One simple Python REST endpoint with input validation, a focused test, API documentation, source and setup instructions. It excludes database integration, authentication, deployment and frontend work. Send the endpoint requirements so I can confirm fit.
What tests and documentation will I receive?
All packages include focused tests for the agreed behaviour, documented request/response examples and setup instructions. Database/auth packages also test relevant validation and access rules. This is scoped API testing; load testing and security audits need separate scope.
Is deployment or hosting included?
Premium includes Docker setup and one deployment to one agreed, buyer-owned hosting environment. Hosting, domains, paid APIs and cloud usage are paid by you. CI/CD, multiple environments, infrastructure migrations and ongoing operations need a custom offer.
Can you improve an existing backend?
Yes. Share the framework, repository overview and required endpoints first. I can extend an existing Python backend after checking its condition. For a specific reproducible error, my Python bug-fixing gig may fit better. Large rewrites need a custom offer.
Are frontend screens and unlimited features included?
This gig covers backend REST APIs. Frontend screens, mobile apps, complex payment flows, large data imports and unlisted integrations need separate scope. Endpoint and model limits apply; complex business rules may require a custom offer even within those counts.
How do revisions and handover work?
I deliver the agreed source, API docs, setup instructions and focused tests, then explain how to run and verify the backend. Revisions refine the agreed scope and acceptance criteria. New endpoints, changed requirements and ongoing maintenance are separate work.
