Backend API & Microservices

REST and GraphQL APIs, microservices and cloud backends built for reliability and tested at the API level.

Overview

The backend holds your business rules and data. When it fails, everything built on top of it fails too, which is why backend code needs tests at the API level, not just through the UI.

We design and build APIs and services with clear contracts, secure authentication and automated tests, and deploy them with monitoring so problems are caught early.

What we do

  • 01

    Design APIs and data models

  • 02

    Build REST or GraphQL services

  • 03

    Handle authentication, permissions and integrations

  • 04

    Write automated API and integration tests

  • 05

    Deploy to the cloud with monitoring

How we work

  1. Step 1

    Scope

    We agree goals, features, stack and a sprint plan.

  2. Step 2

    Build in sprints

    Weekly increments from a shared backlog, demoed as we go.

  3. Step 3

    Test every sprint

    QA tests each feature as it lands and automates the core flows.

  4. Step 4

    Launch and support

    We release, monitor and fix, and hand over code your team owns.

Who it's for

Questions

REST or GraphQL?+

Both work well; the right choice depends on your clients and data. We'll recommend one for your case.

Should we move to microservices?+

Not always. Microservices add complexity; we'll tell you honestly whether they're worth it for your scale.

What does it cost?+

Hourly work starts from $25/hr. Fixed-price projects and dedicated teams are quoted after a free scoping call, based on scope, platforms and timeline.
