I will build a secure fastapi backend with postgresql and redis
Sagnik Santra
About this gig
Your startup doesn't need another tutorial-style CRUD API. It needs a FastAPI backend that won't break when real users show up.
I build REST APIs with FastAPI, PostgreSQL, and Redis. Every project ships with JWT auth, role-based access control, and automated Pytest coverage; untested code is a liability with a due date.
What you get:
- Async FastAPI REST API modeled around your actual data
- PostgreSQL with SQLAlchemy and Alembic migrations
- Redis caching and rate limiting where they matter
- JWT authentication with proper password hashing
- 80+ automated tests on Premium
- Swagger docs, plus Docker and Render deployment on higher tiers
Why work with me:
- 1,000+ completed projects and 600+ five-star reviews as a Fiverr seller taught me how to communicate clearly, deliver on time, and scope work properly.
- I'm now applying that same discipline to backend development, starting with a short brief before I write a line of code.
How it works:
Message me your requirements directly before placing the order; I confirm scope with a quick brief, then you get real progress updates until delivery.
Doesn't the project fit a package? Message me first, and I'll scope it properly.

I discovered code the way you discover a hidden track on your favorite album—by accident, and then completely by obsession.
Soon, I was building. Not because I had to, but because I couldn't stop. FastAPI felt different—clean, intuitive, powerful.
Before this, I spent 4 years as a freelance writer and designer—1200+ projects, 500+ five-star reviews. That taught me deadlines, communication, and what clients actually need: someone who delivers.
Now I build backends that don't break: real-time APIs, clean architecture, production-ready systems.
Let's build something that matters together.

FAQ
Do I need to know technical details to work with you?
No. I'll ask you about your data, users, and business logic. I translate that into API endpoints. You just review the spec and say yes or no.
Can you modify an existing API?
Yes, but I need access to the codebase and a clear list of changes.
What if I need changes after delivery?
I offer three free rounds of revisions per package. Additional changes are quoted separately.
What if I need more endpoints than the package includes?
Message me before ordering. I'll quote a custom price based on the scope.
Do you deploy the API to a live server?
Yes, Premium includes Render deployment. Standard and Basic include Docker setup.
What databases do you support?
PostgreSQL is my default. I can also work with MySQL or SQLite on request.
Do you write tests for the code?
Yes. Basic includes basic tests. Premium includes 80+ automated tests with Pytest.
How do I know you're capable of handling my project?
Check the gig gallery for project screenshots and architecture samples I've uploaded. The best way would be to speak to me directly. So please go ahead and send me a direct message. Ready to answer any questions.
