What a FastAPI developer does on our teams
A FastAPI developer owns a Python service from the data model to the deployed container: Pydantic models that define the contract, SQLAlchemy and Alembic for the database, background workers for slow jobs and an OpenAPI schema that front-end teams generate clients from. In our case studies FastAPI runs the machine-learning search service for Cuts Like A Knife and the Python side of GovDoc AI.
How we assess FastAPI developers
- API design: typed request and response models, error handling, pagination and versioning
- Async judgement: when async database and HTTP calls help and when they only add complexity
- Data: SQLAlchemy 2 models, Alembic migrations and query performance on PostgreSQL
- Testing: pytest fixtures, httpx test client and contract tests against the OpenAPI schema
- Sample task: a FastAPI service with two related resources, a background job and tests, in three hours

SolasEnterprise · OperationsHiring FastAPI developers, answered.
FastAPI or Django?
FastAPI suits API-first products, AI and data services and anything that benefits from typed contracts. Django suits content-heavy apps that want its admin, ORM and auth out of the box. Our Python developers work in both.
Can they build the front end as well?
Many of them pair FastAPI with a Next.js or React front end. If the front end is the larger share, a full-stack developer may be the better hire.
Do they handle deployment?
Yes. They containerise the service, set up CI, migrations and health checks, and deploy to your AWS, GCP or Azure account.
