Backend and API development

“My app needs the machinery behind it.”

A backend that gets the job done

Your interface needs somewhere to send data, run business rules and connect to other tools. I build the backend around that workflow, with clear API contracts so the pieces can work together.

The button is the easy bit. Something still has to happen when you press it.

Tell me the problem. I'll explain the possible approach and the next step, before any work is agreed.

What you get

  • Backend APIs for an agreed workflow
  • Data validation and application access controls
  • Connections to authorised third-party services
  • API documentation, testing and source handover

Before you hire me

The practical details, before a project becomes a project.

Do I need all the content ready?

Bring what you have: the problem, any existing site or tool, and the content you already use. Before work starts, I identify what is missing and agree who supplies copy, images and other assets. Copywriting and custom illustration need their own agreed scope.

Do I get the source code?

Source handover is part of the service. Before starting, I agree the deliverables and ownership terms, including any third-party software or assets with their own licences.

What costs continue after launch?

Depending on the project, domains, hosting, business email, paid services and AI usage may have recurring costs. I identify the services the project needs and discuss those costs separately from the build before agreeing the scope.

What about maintenance and later changes?

I discuss maintenance and handover before launch. Support, new features and changes beyond the agreed scope are quoted separately; ongoing support is something to agree, rather than assume.
