I will build a rest api backend in node js, typescript or fastapi


About this gig
I build backends that don't fall over. You describe what the product needs to do. I design the database schema, build the API, secure it, document it, and deploy it somewhere you can actually use it.
Stack: Node.js with TypeScript (Express, Prisma) or Python with FastAPI. PostgreSQL, including migrations and indexing. JWT auth, refresh tokens, role-based access control. Docker, deployed to Render, Railway or Fly. OpenAPI/Swagger docs, so your frontend developer isn't guessing.
Recent work: a 3-service trading platform, REST API, PostgreSQL with pgvector, payment integration, scheduled jobs and a separate AI service. And a CI/CD runner that queues Docker builds through Redis and streams logs over WebSockets. I can show you both running.
I write code you can hand to the next developer: typed, organised by feature, with a README that explains how to run it. You own all of it on delivery.
Message me with what you're building before you order and I'll tell you which tier actually fits, including if the answer is none of them.

FAQ
Do you write tests?
Yes. Unit tests for business logic, integration tests for the API endpoints. I'll tell you the coverage before delivery.
Who owns the code?
You do, fully, on final payment. No license fees, no retained rights on my side.
Can you work inside my existing codebase?
Yes. Send me repo access and I'll match your existing patterns instead of imposing my own.
What if the scope grows halfway through?
We agree on the extra scope and price before I build it. No surprise charges at delivery.
