I will build fast api or flask api and rest api in python


About this gig
Need a FastAPI or Flask backend built fast? I build clean, scalable REST APIs in Python from a single endpoint to a full authenticated backend with database integration.
I'm a Python developer with hands-on experience in backend development, API design, and AI integration. I write code that's well-structured, documented, and ready to deploy.
What I can build for you:
- FastAPI Backends fast, modern, async-ready REST APIs
- Flask APIs lightweight backends for smaller projects
- Authentication JWT/token-based auth and authorization
- Database Integration PostgreSQL, MongoDB, SQLite, and more
- API Documentation Swagger/OpenAPI auto-generated docs
- Bug Fixes & Optimization improve existing backend code
Every delivery includes:
- Clean, commented Python code
- requirements.txt for easy setup
- API documentation
- Revisions until you're satisfied
Why work with me:
Fast turnaround, clear communication, and code that's built to scale not just to work once.

FAQ
Do I need to provide hosting or deployment?
No, I deliver the code ready to run. If you need help deploying it (Docker, cloud platforms, etc.), let me know and we can discuss that separately.
Can you work with my existing codebase?
Yes — send it over before ordering and I'll review it to scope the work accurately.
What database do you support?
PostgreSQL, MongoDB, SQLite, and most common databases. Let me know your preference in the requirements.
Will I get API documentation?
Yes, FastAPI generates Swagger/OpenAPI docs automatically. For Flask, I'll add documentation using Flask-RESTX or similar.
