Custom Web App

A custom web app from haldev studio starts at £3,000+ and is quoted to your specification. It suits work that goes beyond a standard website — booking systems, dashboards, member portals, and internal business tools.

The final quote depends on the features, data model, and integrations involved. If I can't build it, I'll tell you before you pay anything.

Examples of What I Can Build

Not an exhaustive list — just things I've done or know I can do.

📅

Booking system

Appointments, calendar sync, booking form, automated reminders. For holiday lets, charters, mobile services, and hospitality.

📊

Dashboard / reporting

Pull data from multiple sources into one view. Charts, tables, exports. For businesses that want to see the numbers.

🔒

Member portal

Private area with content, directories, event signups. For clubs, associations, membership organisations.

🤖

Tool / utility

A calculator, a generator, a workflow helper. Something that doesn't exist yet but should.

What's Included

Every project is different, but this is the typical scope.

Built to your spec

We agree what it needs to do. I build it. No templates, no assumptions.

User accounts & login

Register, log in, password reset. Role-based access if needed.

Database

PostgreSQL — your data, your control. Properly backed up.

API integrations

Connect to Stripe, Google, OpenStreetMap, or whatever service your app needs.

Admin dashboard

See data, manage users, view reports — whatever your app needs to manage.

Responsive UI

Works on desktop and mobile. Built with Next.js + Tailwind.

Hosting & deployment

Cloud-hosted, set up to auto-deploy when changes are made. I manage the technical side.

Ongoing maintenance

When you need new features or changes, I can add them. No retainer required — just a conversation and a quote.
