Product Designer with a background in industrial design. I think in systems, design with intent, and build things that work.

About

Cross-discipline.
End to end.

I studied Product Design at Loughborough University — which means I came into digital with a grounding in design thinking, systems, and how things actually get made. That industrial design background changes how I approach problems. I'm not just designing screens, I'm thinking about the whole experience.

Every decision I make — from one iteration to the next — is purposeful. Whether it's grounded in research, validated by data, or centred around the end user, there's always a reason. That's something I care about and push for regardless of the constraints around me.

Currently at Accenture, embedded in JLR's digital team, working across UX strategy and UI delivery for one of the world's most premium automotive brands.

Two UX case studies and a body of UI work — enterprise UX strategy at Accenture, a full site designed and built from scratch, and brand campaigns delivered for JLR across Range Rover and Land Rover.

Approved Used

JLR · UX/UI Designer · Accenture · April 2026 – Present

JLR had a growing backlog of approved used stock. With retailers unable to bring in new vehicles until existing inventory moved, shifting approved used became a commercial priority — not just a UX one. My role was to audit the current digital entry points across Range Rover and Land Rover, understand why users weren't engaging with approved used, and propose changes grounded in data.

UX Audit Analytics Competitor Analysis CX Strategy Heatmapping

The Brief

"Assess the current entry points and identify opportunities to boost visibility primarily across Range Rover and Land Rover DX sites."

The Problem

JLR's approved used backlog was blocking retailers from taking in new stock. To unlock the pipeline, they needed to sell more approved used vehicles — which meant making that option visible and compelling to users who were arriving on new car pages.

Key Findings

—
Significant crossover between new and approved used audiencesA meaningful proportion of users arriving on new car pages were already considering approved used — the opportunity wasn't being captured.
—
New car entry points drove more approved used sessions than dedicated DXUsers were arriving at approved used via new car pages far more than via dedicated approved used entry points.
—
Drop-off between PLP and PDP was a key point of failureUsers browsing approved used listings weren't converting through to product pages — pointing to a gap in perceived value at the listing level.

Recommendations

1
Build a considered journey into approved used BuiltRather than dropping CTAs into the new car flow, guide users through the value of approved used first — why it exists, what they get — then route them to the order site once they're informed and bought in.
2
Combine new & approved used on results pages BuiltReduce the cognitive switch required — surface both options together so users can make an active, informed choice rather than having to navigate away.
3
Surface vehicle value on PDP earlier ExperimentalLead with specs, features, and selling points higher in the page — give users a reason to commit before they reach the CTA.

Outcome

2 of 3 shipped

Recommendations 1 and 2 were adopted and built into the Range Rover and Land Rover sites — the considered journey (signpost, extended Discovery component, ignite-bar entry) and the combined results page, starting with the contained, measurable phase. Recommendation 3 was positioned deliberately as an experiment to widen the client’s thinking beyond entry points, and remains open.

What I took from it. Anchoring every change to a number the client already trusted made the recommendations easy to say yes to, and sequencing them from lowest risk upwards meant the structural idea never had to win on its own. Next time I’d pair the analytics with a small round of user interviews earlier — the data showed where users switched, not why.

NHN Horizon

Commodity Trading · UX, UI & Front-end Build

A full website design and build for a commodity trading company operating across two distinct markets — agriculture, sourcing from Northern Nigeria and East Africa for wholesale buyers in the Middle East, and oil & gas in the Nigerian market. Competitors in this space run static, linear sites with a formal, information-led tone, and the site needed to sit credibly in that landscape while giving each audience a tailored experience without fragmenting the brand. I took it from positioning and competitor research through to a Figma design system and a React build. NHN Horizon is a venture of my own, which meant the commercial trade-offs were mine to make as well as the design ones.

The Problem

Wholesale buyers in commodity trading decide whether a supplier is credible within seconds of landing on their site — and they expect the conventions of the sector. NHN Horizon serves two very different audiences, agriculture and oil & gas, from one small company. The site had to establish trust with both without looking like two businesses, and it had to work as the front door for outbound outreach, where a prospect arrives from an email with no prior context.

The Challenge

—
Design language constrained by conventionCompetitors in commodity trading run static, linear sites with a formal, information-led tone. NHN Horizon needed to sit comfortably in that landscape — familiar enough to build trust, considered enough to stand out.
—
One brand, two audiencesAgriculture and oil & gas clients have different expectations, vocabularies, and trust signals. The site needed to feel native to both without splitting into two separate products.
—
Competitor research across both sectorsBenchmarked trading platforms in agriculture and energy to understand conventions, identify gaps, and inform the visual and structural decisions.
—
Designing for the outreach journey, not just the browseMost first visits come from outbound emails to prospective buyers, so each sector’s landing view had to answer “who are you, what do you trade, and why should I reply?” above the fold — before any navigation.

Outcome

Live & in use

Shipped end to end — designed in Figma, built in React, and live as the front door for the company’s outreach to wholesale buyers, with each sector given its own entry point and visual register within one brand.

What I took from it. Designing for two audiences forced a discipline I now apply everywhere: decide what is shared and what is sector-specific before drawing anything, or the two experiences drift apart. Building it myself also changed how I hand over to developers — I now know which design decisions are cheap and which quietly cost a week.

Experience 01

Agriculture

Grounded in trust and provenance — an earthy, assured visual language that speaks the language of agricultural commodity traders. Warm tones, clear market information, and a tone of reliable expertise.

Experience 02

Oil & Gas

Precise, technical, and commanding — a darker, industrial feel that meets the expectations of energy sector professionals. Clean data hierarchy, authoritative tone, and a focus on scale and reliability.

UI Work

Range Rover
UI Collection

Three campaigns delivered across the JLR engagement. Each had its own constraints — tight deadlines, strict brand guidelines, a premium bar that couldn't slip. The challenge wasn't coming up with ideas, it was executing to a standard where every asset feels native to one of the world's most recognised luxury brands.

UI Design · Asset Integration
London Editions
Four edition pages, each rooted in a London borough — Westminster, Belgravia, Battersea, Hoxton — on a one-week turnaround. I worked directly with a copywriter so that image, crop and type carried the same feeling as the words: each page had to feel like the place it was named after, not just say it. Every decision came back to one question — does this belong in the Range Rover world?

UI Design · Campaign
Range Rover Event
A campaign landing page and countdown experience. The brief came with a fixed set of assets from the social team, so the premium feel had to be built through hierarchy, pacing and restraint rather than new imagery. The harder problem was that entry points were scattered across the DX sites — the landing page had to make sense wherever a user arrived from.

Promotional Content
Promotional pieces for Goodwood Festival of Speed, the Chelsea Flower Show and the Range Rover SV Ultra, each turned around in a matter of days. The job was to make an external event feel like a Range Rover moment — foregrounding the event without diluting the brand — and to do it fast enough that it landed while the event was still live.

How I work

Reasons, not opinions.

Start from the number
Session data, heatmaps and click share before any layout. If I can’t point to what a change is meant to move, it isn’t ready to be proposed.
Sequence by risk
Ship the contained, measurable change first and let it earn the structural one. Clients say yes to a small step far more readily than to a big idea.
Design inside the brand
Strict guidelines are a constraint I like. The craft is making every asset feel native to the brand, with copywriters, social and brand teams in the room from the start.
Build it, or build for it
Having taken a site from Figma to React myself, I hand over in components and states rather than pictures, and I know which decisions are cheap and which cost a sprint.

Let's make
something
worth seeing.

Open to new opportunities in UX and product design. I'm looking to work with teams where design decisions are taken seriously — where research informs direction and the standard of craft actually matters.
