I will build a rest API backend with fastapi and postgresql


About this gig
Need a backend for your app, MVP, or internal tool?
I build REST APIs using FastAPI and PostgreSQL clean, working, documented, and ready to connect to your frontend. I recently built and deployed a FastAPI backend that processes financial documents, integrates with PostgreSQL, and uses an LLM for document analysis with conversational follow-up you're welcome to see it in action before you order (link in portfolio).
What I build:
- RESTful APIs with FastAPI
- Data validation with Pydantic
- Database integration (PostgreSQL, SQLite)
- JWT authentication
- AI/ML API Integration
- Frontend To Backend Integration
- Clean, documented, working code not just a code dump
How I work:
- I keep all communication on Fiverr
- You get source code, a short setup guide, and API docs
- Message me before ordering so I can confirm scope fits your needs this avoids surprises on both sides
Let's talk about what you're building.

FAQ
Do you deploy the API to a live server?
Deployment guidance is included on Premium (getting it running on a platform like Render or Railway). Full production infrastructure (AWS, Docker, custom domains) isn't included by default — happy to discuss as a custom offer if you need it.
Can I see an example of your work first?
Yes — I have a deployed FastAPI project (financial document processor with PostgreSQL + LLM integration) linked in my portfolio. Feel free to check it out before ordering.
What if I need more resources/endpoints than the package includes?
Message me your requirements before ordering and I'll either recommend the right package or send a custom quote — I'd rather scope it correctly upfront than leave you short mid-project.
Do you provide support after delivery?
I'll help you get the code running correctly. Ongoing feature additions or maintenance beyond that would be a separate, clearly scoped follow-up order.
