My Services

Just a selection of the services I provide…

Responsive Web Design

I build responsive websites using HTML5, CSS (Sass or LESS). With some websites reporting half of their visitors using a non-desktop device, it's important to optimise websites for both mobiles and tablets.

Web Performance

Performance is vital to a sites success and it's often overlooked. Fast and optimised pages lead to higher visitor engagement, retention, and conversions.

CSS Architecture

Good organisation of CSS on a large website has several benefits which could save countless hours of development time. A solid CSS architecture ensures quality code and reduces maintenance.


I've been using WordPress for several years and it's still my favourite Content Management System. It's highly scalable, easy to use and is perfect for almost everything, including ecommerce.

“Callum’s knowledge, attention to detail, and high quality web development is second to none. He not only provides a personal and responsive service but ensures a depth of understanding of your needs, goals and limitations. Everything we agreed on has been delivered on time, and I’m very impressed with the site and the ongoing service and development he is providing. I have recommended him to many of my business contacts, and I can’t say enough about the quality of his services.”
