FastAPI or Node.js for our backend?

If your backend does a lot of AI, data or scientific work, FastAPI keeps you in the Python ecosystem those tools live in. If your team is all TypeScript and the backend is mostly CRUD and integrations, Node.js is often simpler. Many products run both.

Can FastAPI handle production traffic?

Yes, when deployed properly — multiple workers behind a process manager, connection pooling, and slow work moved to background jobs. We set this up as part of the build.

Do you write tests for FastAPI services?

Yes. API tests with pytest against a real database, contract tests on the OpenAPI schema where front ends depend on it, and CI that runs them on every change.

Hire FastAPI Developers

Python backend engineers for fast, typed APIs — including the ones that sit behind your AI features.

Get Matched with a Developer

FastAPI has become the default Python framework for new APIs, and especially for AI backends: async by design, typed with Pydantic, and close to the Python AI ecosystem. Our engineers build FastAPI services with proper project structure, database migrations, auth, background processing and observability — the parts that tutorials skip and production depends on.

What clients hire our FastAPI engineers for

AI and LLM backends

Streaming chat endpoints, RAG retrieval services, agent runtimes and document-processing pipelines that your web or mobile front end calls.

Product APIs

REST APIs for web and mobile apps with auth, role-based access, pagination, OpenAPI docs and generated client types.

Data and integration services

Webhooks, scheduled sync jobs and internal APIs that move data between your systems reliably, with retries and idempotency.

FastAPI skills we staff for

FastAPI, Pydantic & async Python

PostgreSQL with SQLAlchemy / asyncpg & Alembic migrations

Background jobs (Celery, Cloud Tasks) & webhooks

Streaming (SSE) responses for LLM features

Auth: JWT, OAuth, Firebase Auth

Docker, Cloud Run & CI/CD

When it’s worth bringing in FastAPI expertise

Hire a FastAPI developer when you need a Python backend for AI or data-heavy features, when an existing Flask or Django API is struggling with async workloads, or when your product needs a well-documented API that web, mobile and partner integrations can share.

Flexible Hiring Models

Hourly

Pay only for the hours you need. Ideal for short tasks, fixes, and overflow work.

Dedicated (Monthly)
