Tools change, craft stays. I’m also fluent in Jira, Confluence, and Google Workspace, and I keep learning.
A few words from people I’ve worked closely with.
I worked with Jon for 5 years, and he always demonstrated an incredibly strong work ethic and a thoughtful approach to tackling design solutions.
As design and technology evolved, Jon always made sure he was on top of it and learning as much as he could. His knowledge in design systems and complex applications is where he thrives. Always putting the user at the head of the table, whilst bridging the gap between design and development.
– Tristan Dexter
Chief Experience Officer at Jurnii
I highly recommend Jonathan as a designer and as a colleague. He is incredibly hard-working, deeply committed, and someone you can always rely on to see things through. He has a strong and thoughtful design systems mindset, with a fundamental understanding of how to build work that scales and lasts. Beyond his skills, Jonathan brings a friendly, positive energy to any team, and his well-known love of cats perfectly mirrors his approach to design: patient, detail-oriented, and quietly thoughtful. He is genuinely a pleasure to work with and an asset to any design organisation.

Jonathan is a lovely, level-headed and easy-going person to work with! Would highly recommend working with him for his adaptability in collaborative work and his always-up-to-date knowledge in his field!

Jon combines sharp visual design with a strong UX mindset and a rare level of consistency. He understands requirements quickly, takes direction with ease, and always delivers, while raising the bar for the whole team.

If you need a designer who can lead, systemise, and ship, without losing craft, let’s talk. I’m strongest where UX, UI, and design systems meet.
