Freelance Front-End Developer

With deep expertise in HTML, CSS, and JavaScript, I build user interfaces that are quick to load, easy to use and work cross-browser and cross-platform.

Freelance Front-End Developer for High-Performance, Accessible Web Interfaces

Looking for a freelance front-end developer who can deliver high-quality, accessible and high-performance web interfaces? I specialise in building fast, user-centric front ends using HTML, CSS and JavaScript, using modern frameworks like React, classic libraries such as jQuery and build tools including Vite and Webpack.

Whether you're running WordPress, Drupal or a custom backend, I can create a user interface to suit your requirements or develop headless front-end solutions tailored to your business goals and user needs.

Why Choose Me?

As an experienced freelance front-end developer, I combine modern development practices with deep knowledge of browser behaviour, performance and accessibility.

Accessible by Design: I follow WCAG standards to build interfaces that work for all users, including those using screen readers or keyboard navigation.
Performance-Driven Development: Using tools like Vite and Webpack, I write modular, fast-loading code optimised for all devices and connection speeds.
Headless Expertise: I build fully decoupled front ends that connect seamlessly to WordPress, Drupal or custom APIs using REST or GraphQL.
Advanced jQuery Solutions: I have extensive experience developing advanced jQuery interfaces, custom plugins and dynamic behaviours, ideal for projects that require stability, legacy compatibility or complex interactions.

My websites and applications are built with scalability, speed and accessibility in mind. They are designed for broad compatibility and fast performance, ensuring smooth interaction for users across a wide range of devices and connection types.

Recommendations

What more can I say apart from Justin is the best in the business, bar none. Having worked with a number of web developers in my time, it's the attention to detail that sets him apart from all others.
His approach is both clinical and creative. He will listen to all requests, make suggestions where relevant, and - more importantly - never shy away from a challenge when others would. From the over-coded mess that was to be our new website, Justin helped us unravel and develop an ecommerce store that was ready for launch in less than half the time we’d already accrued with our previous developer.
Put simply, to choose anyone else over Justin would be a bad business move. I cannot recommend him highly enough.

There are few better web developers or IT problem solvers than Justin, he is also a skilled creative designer. He took a failing project over and turned it into a successful one within three months. The previous developers had taken six months to create a poorly developed mess. Justin had to unravel it all and find fixes for so many things. He has good knowledge of business and will provide you with a solution that fits your needs. Once he knows where you want to go and what you want to achieve he will find you the best path forward.

Having worked with Justin on a number of projects his work has always been of the highest standard. His skills are versatile and flexible, and his consistent understanding of the details as well as the bigger picture really makes him a valuable addition to the team. From a technical and creative perspective I would gladly recommend him to anyone.

The quality of Justin's work has always been exceptional, exceeding every brief given to him. His knowledge of a wide variety of platforms and programming languages makes him one of the most versatile web designers / developers I know and an incredible asset to any organisation.
