“Avalon took the time to really understand what we needed and turned a complex challenge into something clear and easy to navigate. He worked confidently under a very tight deadline, communicated clearly throughout, and delivered a result we were genuinely happy with. 100% great to work with.”

James Mason
Co founder and Designer at Massif-Studio

"I’ve had the pleasure of working with Avalon across a variety of brands and am always blown away by not only the quality of his work, but the flexibility and open mindedness he approaches each project with. There is a reason I have contracted him at every single business I've worked in which is crying out for a UI/UX expert.

I am a perfectionist admittedly and I can be a bit difficult to work with, but what I love about Avalon is that every piece of feedback is responded with logic and research. If I think something will look or perform better, he'll respond with why he believes X or Y would be better suited and I can never argue with the reasoning, he knows his stuff."

Will Leighton
Marketing Director at The One Glove

“Working with Studio Portolan has been excellent. We have many regular customers praising the new website on how much time they have saved by booking online. On top of that, we have seen an increase in new customers which has provided the business with stability and significant growth.”

Samuel Mousavi-Portolan
Owner at The Jag Workshop

"I am extremely happy with the website that Avalon from Studio Portolan has created for me. It is visually appealing, professional, easy to navigate, and, responsive – everything we asked for in regards to design was perfect. Avalon was a pleasure to work with throughout the whole process and has offered his advice and support post-launch. I have and will continue to recommend Avalon and Studio Portolan to others."

Henry Kent
Founder at Fixed Interest Investments

“He's been a huge part of our Digital team for a couple years now, playing a big role in moving us from Bulk Powders to Bulk we see today. From emails to banners to landing pages and everything in between.

More than that he's been a great guy to have around and I know he'll be missed. I want to thank him for everything he's contributed to Bulk and wish him the best as he moves into freelance and all round creative work."

David Rossiter
Head of UI/UX at BULK™

The SEO of my site has almost doubled since launch, I have to attribute a lot of it to the UX of your design - wicked work! Everyone loves it! Was a pleasure working with you 👊

Avalon brings so much passion and energy to the design process with unique idea, imaginative concepts whilst making all parties feel comfortable through the process. I couldn’t recommend more!

Nic Dunn
CEO at Charle

Working with Avalon has been an exceptional experience from start to finish. We had the pleasure of collaborating with him on two distinct phases of our website development, and his expertise made each step seamless and efficient.

In the first phase, Avalon helped us revamp our site to effectively showcase our system and support a successful pre-order campaign on Kickstarter. His ability to translate our vision into a functional and visually compelling platform played a critical role in connecting with our audience.In the second phase, Avalon spearheaded the development of our fully eCommerce website. Thanks to his deep knowledge and strategic insights, we were able to build an intuitive customer engagement journey, ultimately enhancing the overall user experience and driving growth for our business.

I highly recommend him to anyone seeking a skilled and reliable web developer!

Every aspect of working with Avalon is a joy. Not only is he one of the most genuinely decent people you'll ever meet, he is also one of the most dedicated. He brings everything to a project. Heart and soul.

Avalon is a rare breed of creative person, in that he is brilliantly organised and process driven, without allowing the process to affect his creative instincts. He holds himself to a very high standard in everything that he does, and you can always be certain that he is constantly pushing himself to learn and grow. Choosing to work with Avalon will be one of the better decisions you ever make.

Duncan McRobb
CEO at Undercover Activity
Are you a UX studio, a brand studio, or a development agency?
Arrow

Our core strength is UX and experience design, supported by brand thinking and deep development awareness. We don’t replace your developers — we design systems they can build confidently. That means fewer compromises, fewer rebuilds, and better long-term outcomes.

We get traffic, but conversion is low. Can you help?
Arrow

Low conversion is typically caused by friction, confusion, or a lack of confidence at key moments. We identify where users hesitate, simplify decision-making, and redesign journeys to guide customers naturally toward action — without pressure or gimmicks.

Our brand already looks good. Do we need to change it?
Arrow

Most brands don’t suffer from poor aesthetics, but from unclear communication and weak experience design. We focus on how your brand shows up in structure, messaging, and flow — ensuring customers understand the value quickly and intuitively.

What happens after delivery, do you support ongoing optimisation?
Arrow

After launch, we analyse performance, identify friction, and iterate on what matters most. This can include UX improvements, messaging tweaks, and conversion testing — ensuring the experience keeps improving, not standing still.

Can you work with our existing developers or tech stack?
Arrow

We regularly collaborate with in-house teams and external developers across Shopify, headless stacks, Webflow, and custom builds. Our designs are modular, scalable, and realistic — built to be implemented cleanly, not re-interpreted.
