John Kavanagh

Description

John Kavanagh is a contract and freelance front end web developer based in Brighton, UK, and his site works as both a portfolio and a clear introduction to how he helps teams ship interfaces that feel polished, fast, and dependable. If you are hiring for a short term build, a long term engagement, or a specialist to strengthen a delivery team, this is the kind of portfolio you want to land on, because it speaks directly to the reality of modern front end work. You are not just looking for someone who can write code, you are looking for someone who can turn designs into production ready UI, protect accessibility, and keep performance steady as features grow. The tone of John Kavanagh website is professional without the agency fluff. It is built to make it easy for clients, product leads, and engineering managers to understand what he does, how he works, and what level of finish they can expect. The portfolio highlights the core strengths that matter in real projects: responsive interfaces that behave well across devices, thoughtful HTML and CSS, JavaScript that supports the experience rather than fighting it, and an attention to detail that shows up in spacing, typography, interaction states, and edge cases. If you have ever launched a project where the last ten percent took half the schedule, you know why that detail matters. A strong front end developer also needs to collaborate well, and this site is geared toward that. It signals a developer who can integrate with a team, pick up an existing codebase, and deliver clean components that are easy to maintain. John is often associated with building responsive, accessible, pixel perfect front end work, commonly with modern JavaScript and React, which makes his offering especially relevant for companies shipping design system driven products or marketing sites with high expectations for quality. If your users include keyboard and assistive tech users, if your stakeholders care about Lighthouse scores, or if your designers expect fidelity without endless back and forth, you are in the right place. Because it is a portfolio, it also serves as a shortcut to trust. Clients can quickly see the kind of work John takes on, and they can judge fit without a long sales call. For businesses in Brighton, London, or teams working remotely across the UK and beyond, it reads like a practical invitation: here is the craft, here is the capability, and here is how to start a conversation when you need a front end specialist who can ship.
