FastAPI Development
Typed, fast Python services where throughput and contracts matter.
FastAPI is what you want when a Python service has to be an API rather than an application. Type hints define the contract, validation and OpenAPI documentation are generated from them, and the async foundation handles concurrency that would stall a traditional Python stack.
For serving a model, exposing a data pipeline or building an internal service, it hits a sweet spot: fast to write, fast at runtime, and self-documenting.
Why we use it
We use FastAPI for the Python half of hybrid systems — model inference endpoints, extraction pipelines, anything the main application calls over HTTP. The generated OpenAPI schema means the consuming team can integrate without waiting for hand-written documentation.
We would not build a full customer-facing application on it. There is no admin, no ORM and no conventions for the ordinary parts of a web application, and assembling those yourself is how a small service becomes a bespoke framework nobody wants to maintain.
