Bespoke web apps and booking systems

When a website is not enough, I build the system behind it: bookings, sign-ins, records and the screens your staff use to run it.

Who it is for

Organisations with a job that off-the-shelf software does not fit: a school, a university department, a charity, a small business.

For example a booking system, a members' area, a marking system or a private archive.

What you get

  • A system designed from research with the people who will use it.
  • Sign-in that matches how your organisation works, with the right access for each role.
  • Bookings, payments and tickets, when you need them.
  • The data you already have, moved in safely.
  • A record of who did what, when the job needs one.

How it works

I talk to the people who will use it and watch how they work. I build an early version, test it with them and change it until it fits.

Then I host it, keep it safe and keep it running.

What it costs to run

The running cost depends on how many people use it and how much it has to store. I size each system to run fast on modest hardware.

I do not list prices here yet. Tell me what you need and I will tell you what it costs to build and what it costs to run.

Questions people ask

How long does a web app take to build?

It depends on the size of the job. I use AI tools to speed up the building, then check and test everything myself, so one person can deliver quickly. Tell me what you need and I will give you a date before I start.

Can it work with the systems we already have?

Usually. I connect new systems to existing ones, bring in old data, and set up sign-in with the accounts your people already use.

Who owns the system?

You do. I use standard, widely used tools. If you ever move on, you take everything with you.

Work like this

  • SUMS

    A marking system for a university. Two markers grade each student project without seeing each other's marks, and the system reconciles the two marks automatically. In use since 2018, with about 600 projects and 100 markers a year.

  • Student feedback platform

    A university asked me for a way to collect feedback from students, to replace its old survey software. It runs annual surveys and short pulse surveys for each module. Nobody can trace an answer back to the student who gave it. It is in testing.

  • Photo archive for a school

    A private archive for a school. Artists' photographs are kept in one place so students can learn from them.

  • ASICA

    A research app on a tablet that helps people treated for melanoma check their own skin at home. Designed with patients and run in a six-month NHS pilot with twenty of them. I built the working prototype with a colleague.

For IT people

  • Passkeys and single sign-on

    Passkey login and single sign-on: one identity service for every app, with WebAuthn, OIDC and roles that match how the organisation works.

Tell me what you need

A few lines about the project is enough. I read every message myself. I meet people face to face within about 30 miles of Portsmouth, and work with organisations anywhere in the UK.
