Selected work

Designing clarity into complicated systems.

My work sits where user needs, organisational complexity and technical delivery meet. These examples show the types of problems I solve.

About me

I bridge strategy, interaction design and delivery.

I’m most effective on products where the workflows are complicated, the stakes are high and several teams need to align. I turn research, requirements and technical constraints into clear journeys, scalable components and prototypes people can test.

I work closely with product managers, researchers, subject-matter experts and engineers. My background in front-end design means I consider implementation early, not after the design is finished.

01

Start with the real workflow

Understand how people actually complete the task, including exceptions and workarounds.

02

Reduce cognitive load

Use hierarchy, language and interaction patterns to make complex information easier to act on.

03

Design for inclusion

Build accessibility into components, content, states and testing from the start.

04

Prototype to learn

Use Figma and coded prototypes to expose assumptions before they become expensive.

AI tools

Turning complex problems into seamless experiences, faster.

I use AI to move from ambiguity to testable ideas more quickly—exploring workflows, exposing edge cases, building realistic prototypes and communicating design intent clearly.

ChatGPT Codex Copilot Figma HTML, CSS & JavaScript
01 / CLARITY

Understand the problem sooner

Use AI to organise requirements, map dependencies and compare alternative journeys before committing to a direction.

02 / PROTOTYPING

Build realistic ideas faster

Turn concepts into working HTML, CSS, JavaScript and data-rich prototypes that teams can review and test.

03 / EDGE CASES

Design beyond the happy path

Explore roles, permissions, states, exceptions and realistic data scenarios to uncover gaps earlier.

04 / DELIVERY

Create a clearer route to build

Improve acceptance criteria, pattern documentation and implementation notes so design intent survives delivery.

AI accelerates exploration and production. User evidence, accessibility and design judgement still decide what should be built.

Experience

Enterprise experience, practical delivery.
