PATTERN · API-FIRST + HEADLESS

API-first, so the frontend is never the cage.

Design the API as the product and let any client (web, mobile, partner) consume it. Headless decouples content and commerce from presentation. We build the contract first.

[THE SHORT VERSION]

The contract comes first, the clients follow.

API-first means the interface is designed and documented before clients are built, so web, mobile, and partners all consume the same versioned contract. Headless applies the idea to content and commerce, separating the backend from any single presentation layer. The result is flexibility and clean integration, at the cost of more up-front design.

When it fits
  • Multiple clients sharing one backend
  • Content or commerce that must render across channels
  • Products exposing APIs to partners
[HOW WE BUILD IT]

How we build with Headless & API-first.

01

Scope and fit

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

02

Build on a tested foundation

We integrate Headless & API-first 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.
