Custom Software & SaaS

Software built around how you work

custom software
  • Overview
  • What you get
  • How it runs
  • Stack
  • Working together

Overview

We design and build complete software products: the data model, the API, the interface and the operations around them.

Every engagement starts with the workflow you want to change, not the feature list. We ship to a staging environment from the second week, so you can see progress instead of reading about it.

Also inside this service: Product discovery, UI/UX design, Multi-tenant architecture, Billing and subscriptions, QA and test automation.

What you get

  • A production system, not a prototype
  • Typed API and documented data model
  • Automated tests on every change
  • Admin tools for your team
  • Handover docs and runbooks

How it runs

  1. Discoveryusers, data and risks
  2. Designflows tested with real users
  3. Buildtwo-week releases to staging
  4. Launchmonitoring, on-call and iteration

  • Node.js
  • PostgreSQL
  • GraphQL
