Web applications
built to last.
I'm Dave Wilson — an independent developer with over 30 years of experience building bespoke, production-ready web systems. From e-commerce platforms to enterprise tooling to cloud-connected data applications — delivered with full ownership, no middlemen.
Services
E-Commerce Development
Custom storefronts with cart, checkout, promotions engines, and fulfilment integrations. Built for performance and conversion — not templated solutions that box you in.
Enterprise Web Applications
Internal management systems covering HR, timesheets, project tracking, and role-based access control. Integrated with Microsoft 365, Azure AD, and corporate identity platforms.
Cloud & API Integration
Connecting your application to the services that matter — payment gateways, shipping carriers, Azure cloud services, Microsoft Graph API, mapping platforms, IoT data feeds, and more.
Data Platforms & Dashboards
Multi-source data aggregation, reporting dashboards, and operational monitoring systems. From IoT sensor networks to financial reporting — making data useful in real time.
Progressive Web Apps
Mobile-first PWAs with offline capability, push notifications, and native app feel — without app store overhead. REST APIs designed for performance and longevity.
Legacy Modernisation
Extending and improving existing systems without breaking what works. I'm at home in long-lived codebases — adding new capability, improving performance, and reducing technical debt pragmatically.
Off-the-shelf fits nobody perfectly.
Every business is different. Your processes, your customers, your competitive advantages — they're unique to you. A bespoke system is built around the way you work, not the other way around.
Think of it like a suit. An off-the-peg suit fits most people reasonably well. A bespoke suit, cut specifically for you, fits perfectly — and it shows. The same is true of software.
Built around your workflow
You don't adapt to the software — the software adapts to you. Every feature, every screen, every process is designed around how your team actually works.
Scales with your ambitions
Off-the-shelf products grow in directions their vendor chooses. A bespoke system grows in the direction you choose — shaped by your strategy, not a product roadmap.
No unnecessary complexity
Generic platforms come loaded with features you'll never use — and licensing costs for all of them. A bespoke system contains exactly what you need, nothing you don't.
Integrates with your world
Your bespoke system can connect to any service, platform, or data source relevant to your business — not just the integrations a third-party vendor has chosen to support.
No ongoing licence fees
SaaS subscriptions compound over time. A bespoke system is an asset you own outright — the investment pays for itself, often within a year or two of what you'd otherwise pay in licences.
Competitive advantage
When your competitors are all running the same off-the-shelf platform, your bespoke system becomes a differentiator — a tool built to give you an edge, not level the playing field.

What you actually get
Direct ownership
You work with me, not a team of rotating juniors. I write the code, make the decisions, and take responsibility for the outcome.
Production focus
I build for real-world use — performance, security, maintainability. No proof-of-concept shortcuts that become technical debt six months later.
Full-stack breadth
From database schema to cloud config to front-end UX. No handoffs, no gaps, no "that's not my area."
No tech speak
I don't hide behind jargon. Whether we're discussing a simple change or a complex architectural decision, I communicate in clear, plain English — so you always know exactly where things stand.
Business-first understanding
I take the time to listen and gain a deep, meaningful understanding of your business from the ground up — before writing a single line of code. The right solution starts with the right understanding.
Long-term partnerships
I foster lasting relationships with clients, with systems that continue to evolve over many years in response to changing requirements — both internal and legislative. I'm not here for a quick project; I'm here for the long run.
What clients say.

Get in touch
If you have a project in mind — or a problem you're not sure how to solve — drop me an email. I'm happy to have an informal conversation before any commitment.
