Product design · growth · delivery

I solve product and business problems through design and evidence.

I work across product, marketing and operations. I use design judgement, data and AI to find gaps, build useful solutions and help teams move work forward.

01 / Selected work

Work that moved from ambiguity to something real.

These are concise case notes rather than polished success stories. They show the problem, my contribution and the evidence available today.

01

3X4 Health · Product design

Making complex genetic results useful in everyday life.

Live on iOS & Android
Launched June 2025

The problem

Translate a dense genetics report into an educational and engaging consumer experience without losing the substance behind the science.

My contribution

As the product’s sole designer, I shaped the information architecture, visual experience and product journeys. Later work included the Genes First Plan, which turns a user’s results into focused food, supplement and lifestyle actions.

What shipped

A live cross-platform product that lets customers explore their genetic results and act on personalised guidance. The work continues through new features and product learning.

3X4 Genetics · Web design & delivery

Rebuilding a large ecommerce site without disrupting the business.

Launched 9 September 2026

The problem

The existing Shopify site needed a complete visual rebuild and a leaner implementation while retaining the company’s core content and commercial journeys.

My contribution

I redesigned and rebuilt more than 190 pages, using AI to accelerate implementation and QA. I owned the visual system, page delivery, optimisation and launch checks.

What we know

The rebuilt site launched on 9 September 2026 without disrupting the core sales journeys, and the team now works from one consistent visual system.

3X4 Genetics · Growth analysis

Finding the gap between awareness and purchase.

Plan in implementation

The problem

Awareness and sales existed, but the journey between them did not give prospective customers enough education or reason to buy.

My contribution

I brought marketing data from multiple platforms into one analysis, mapped the funnel and identified the middle-of-funnel leaks and content gaps.

What changed

I turned the diagnosis into a prioritised plan with a measure attached to each change. The team is now implementing it.

Purchase

A disconnected set of signals became a measurable plan.

Simul · Independent product

Taking a creative tool from personal idea to paying customers.

Live on iOS & Android

The idea

A simple camera and darkroom for people who want the feel of film without turning the process into a technical exercise.

My contribution

I shaped the product, brand, interface, website and launch. I used AI-supported development to move from design into a working cross-platform app.

Why it matters

In the 90 days to 16 September 2026, Simul had 170 App Store downloads and 14 in-app purchases. It gave me direct responsibility for the whole path from product decisions to acquisition and customer behaviour, and it is one of three apps I have shipped solo.

Product, brand and launch created independently.

Company work is described at a high level to protect internal data, customer privacy and the wider team’s contributions. Recent company work is too new for attributed results, so I show what shipped rather than claim uplift.

02 / How I work

Design eyes. Structured thinking. Evidence over guesswork.

I’m most useful when a problem crosses team boundaries and needs someone to make the whole system easier to see.

  1. 01

    Find the real problem

    Bring the available context, behaviour and business constraints together before deciding what to make.

  2. 02

    Give it structure

    Turn difficult information into a journey, interface or operating plan people can understand and use.

  3. 03

    Close the delivery gap

    Use implementation skills and AI to prototype, build and QA more of the solution myself.

  4. 04

    Measure what changed

    Define useful signals, separate evidence from assumption and use what we learn to choose the next move.

03 / About

A designer who likes to understand the business around the screen.

I have eight years of design experience and have spent the last seven working across product and marketing at 3X4 Genetics. My work has grown from visual design into product thinking, funnel analysis, implementation and the systems that connect them.

I’m looking for a team where thoughtful people solve meaningful problems together. I value direction, honest feedback and enough trust to take ownership.
