What we build

Pick the shape of the problem

Most custom software falls into one of these five shapes. Choose the closest and see what gets built, and where the work actually sits.

Where the work sits

  • InterfaceWeb app, admin, mobile
  • APIAuth, rate limits, versioning
  • ServicesBusiness logic and jobs
  • DataDatabase, files, reporting
  • IntegrationsCRM, payments, vendors

Highlighted layers are where most of the build effort lands for this kind of project.

SaaS platforms

A product you sell to your own customers, with subscriptions, tenants and roles built in from the start.

What you get

  • Multi-tenant architecture
  • Subscriptions and billing
  • Roles and permissions
  • Admin and usage analytics

Typical stack

Next.js · Node · PostgreSQL · Stripe

How we deliver

Working software every two weeks

Custom software goes wrong when nobody sees it until the end. Every sprint here finishes with something real you can use and redirect.

  1. 01

    Discovery

    We map your workflow, the systems involved and what success looks like, then agree the scope in writing.

  2. 02

    Architecture

    Data model, integrations and infrastructure planned up front, so nothing needs unpicking in month three.

  3. 03

    Sprint build

    Two-week sprints, each ending with working software you can click through — not a status report.

  4. 04

    Testing and QA

    Automated tests, code review and security checks run on every change before it reaches your users.

  5. 05

    Release

    Deployed to your own cloud with monitoring, backups and a rollback path if anything misbehaves.

  6. 06

    Support and iterate

    Hosting, monitoring and new features as you learn — or a documented handover to your own team.
