Backend Web Development and Custom Web Apps

When an off-the-shelf tool cannot do the job, we build the thing that can — properly architected, documented and handed over.

Software built for one business

There comes a point where the spreadsheet, the plugin stack and the manual workaround cost more in wasted hours than a purpose-built tool would. That is usually when clients call us.

We build client portals, booking and quoting systems, internal dashboards, membership platforms and integrations that make separate systems talk to each other.

Architecture that ages well

Requirements change. We design for that: clear separation of concerns, database schemas that can be extended without rewrites, and API-first thinking so a future mobile app or partner integration does not mean starting again.

Every project ships with automated tests on the critical paths, so the feature you rely on does not silently break when something unrelated is changed six months from now.

Security taken seriously

Parameterised queries, input validation, output escaping, sensible authentication, role-based permissions and dependency scanning as standard. For projects handling personal data we walk through the GDPR implications explicitly rather than leaving it to chance.

Documented for whoever comes next

You get architecture notes, API documentation, environment setup instructions and commented code. If another developer picks this up in two years, they can. That is a deliberate part of what you are paying for.

Why it matters

What Backend Web Development and Custom Web Apps actually changes for your business

Fits your actual process

Software shaped around how your business works, rather than a process reshaped to fit someone else's product.

Scales without a rewrite

Architecture and database design that accommodate growth and new requirements.

Connects your systems

Integrations with CRMs, payment providers, ERPs and third-party APIs so data stops being re-keyed by hand.

Tested where it matters

Automated coverage on critical paths, so regressions are caught before your users find them.

Secure by default

Input validation, safe queries, role-based access and dependency scanning built into the process.

Genuinely handed over

Documentation, architecture notes and clean code, so you are never dependent on us to continue.

How it works

From first call to measurable result

  1. 01

    Technical discovery

    We map the current process, the data involved and the integration points, then write a specification you sign off before estimating.

  2. 02

    Architecture

    Data model, system design and technology choices documented and explained in plain terms, with the trade-offs made explicit.

  3. 03

    Sprint development

    Two-week cycles with a working staging environment from the first sprint, so you see progress rather than status reports.

  4. 04

    Integration and testing

    Third-party connections wired up, automated tests written, edge cases worked through deliberately.

  5. 05

    Security review

    Authentication, permissions, data handling and dependencies audited before anything goes near production.

  6. 06

    Deployment and handover

    Production deployment, monitoring, documentation and a working session with whoever maintains it next.

Questions

Backend Web Development and Custom Web Apps — your questions answered

Costs, timelines and what happens after we hand over.

Still not sure?

Ask us anything on a free 30-minute call. No pitch, no obligation.

Mostly PHP 8 with Laravel or WordPress, Node.js where real-time matters, and MySQL or PostgreSQL. We choose based on what fits the problem and what your team can maintain — not on what is fashionable.

Fixed price against a signed specification. We invest properly in the discovery phase precisely so the estimate is reliable, and anything outside the agreed scope is quoted separately before work starts.

Usually. We start with a paid audit to establish what state it is in, then give you an honest recommendation — sometimes that is to extend it, sometimes to replace a component, occasionally to leave it alone.

Yes, as a monthly retainer covering updates, monitoring, security patching and a defined allocation of development time. It is optional and there is no lock-in.

That is a normal outcome and we plan for it. The documentation, architecture notes and clean code exist so another team can take over smoothly.
