FastAPI for typed, documented Python APIs.

Typed request and response models, automatic OpenAPI docs, and async performance. FastAPI is our default for Python services, especially AI ones.

[THE SHORT VERSION]

The typed, modern way to write Python services.

FastAPI gives Python the type safety and auto-generated docs that older frameworks lack, with async throughput for I/O-heavy and AI workloads. It pairs naturally with model integration work.

When it fits
  • A typed Python API, especially one serving AI or data
  • Services that need OpenAPI docs for consumers
  • Async, I/O-bound workloads
[HOW WE BUILD IT]

How we build with FastAPI.

01

Scope and fit

We decide where FastAPI earns its place in your system, and where a simpler tool wins. No resume-driven architecture.

02

Build on a tested foundation

We integrate FastAPI against a foundation we trust: typed code, CI, and observability from the first commit. Boring infrastructure, modern surface.

03

Eval before launch

An eval suite proves the build behaves before it reaches a user. We measure, then ship.

04

Handoff with ownership

Your team gets the code, the tests, and a runbook. No lock-in to us or to a vendor framework.
