Backend and API work for a front end you already have

You have the front end. What is missing is the system behind it. I build the database, the admin and the figures page that tells you how the business is doing, and hand over documentation and tests somebody else can pick up.

Press play to watch the real system working, not a mock-up.

This is for you if any of this sounds familiar

You have a site or app, but the real data lives in spreadsheets

The front looks finished and the back is a file being passed around. Two people edit at once and nobody knows which copy is true.

You are an agency or a design-side freelancer

You can deliver the front end but the system behind it needs someone else. I subcontract and sign an agreement not to approach your client.

The old system still runs, but nobody dares touch it

No documentation, no tests, and whoever wrote it has left. Every change is a gamble on what breaks.

Money or another system is involved

Getting this wrong costs money rather than looking wrong. It needs somebody thinking about repeated calls, floods of traffic, and work lost halfway through, from the start.

Three packages. Pick the one that matches what you actually need

These are full project prices, not starting points that grow later. If anything falls outside the scope, I tell you the number before I start on it.

How it works, from first message to launch

1

Send me what already exists

The front end you have built, the spreadsheet you run on, or the old system still in production. Any one of those is enough to start scoping.

2

We agree the data shape before code is written

You get the data structure and the list of what the system will do, to review first. Changing it as a document takes ten minutes. Changing it halfway through the build takes three days.

3

Your team uses the real thing while it is still being built

The system and its documentation open up in stages, so front-end work runs alongside rather than discovering a mismatch at the end.

4

Handover somebody else can pick up

Source code, API documentation, tests, deploy instructions and an admin manual, plus support after delivery.

Questions people ask about this service

We already have a front-end team. How do we connect?

You get an API with documentation you can fire test calls from in a browser, so your team works without asking me one question at a time. We agree the shape of the data in one round before anything is written, so neither side has to rework later.

How is this different from your booking or stock systems?

Those are finished products that arrive with a front end, for owners who want something they can switch on. This is the back end only, for people who already have a front end or a team building one. If you have nothing yet, I will point you at those first because they finish sooner and cost less.

We are an agency. Will you approach our client?

No, and I sign an agreement saying so. The work ships under your name and the documentation is written so you can hand it straight to your client, with my name nowhere in it if you prefer.

What is it written in?

TypeScript and Node primarily. PHP with Laravel and Python are both fine, and if your existing system is one of those I continue in it rather than making you switch to what suits me. Sample code in all three is public and readable before you commit.

How do I know the code is any good?

Judge it on three things you can check: tests that run and pass in front of you, documentation somebody else can work from, and the security review included in Harden. Security work is my main line, so I review my own work before it ships.
