Custom web development when a template won’t cut it
From WordPress plugins to bespoke web applications, we build the technical side of your online presence to do exactly what you need — no more, no less.

Solid development work, explained in plain English
Most businesses reach a point where their website needs to do something a standard theme or plugin can’t handle. That might be connecting to a third-party system, automating a process, or building a tool that’s specific to how you work. That’s where development comes in.
With over 25 years of hands-on development experience, we handle projects large and small — from adding a booking system to an existing site to building a full web application from scratch. Rik writes the code himself.
Extending WordPress beyond what’s out of the box
WordPress powers a large portion of the web for good reason — it’s flexible and well-supported. When you need it to do something specific, custom plugin or theme development is often the cleanest answer.
- Custom plugin development for site-specific functionality
- Theme development and child theme customisation
- WooCommerce extensions and payment integrations
Connecting your website to the tools you already use
If your website needs to talk to your CRM, booking system, stock management or any other platform, we can build that connection. Proper API integrations reduce manual work and keep your data accurate.
- REST API integrations with third-party services
- Webhook setup and automation
- Data sync between your website and back-office systems
Purpose-built tools for specific business problems
Sometimes you need something that doesn’t exist yet — a portal for your customers, a tool for your team, or an application that handles a process unique to your business. We scope, build and deploy these carefully.
- Requirements scoping before any code is written
- Secure, maintainable code with documentation
- Ongoing support and hosting options available
