How I Work
I built a system for working with AI agents, and I run my projects inside it.
I frame the problem and make the calls. Research, design and build run through the system stage by stage, and nothing moves to the next station without a review. Each agent has a defined role and hand-off criteria, and its output is checked separately by another agent. Facts and hypotheses are recorded apart, so any decision can be traced back to why it was made.
-
AX
I design how AI fits into the work: who does what, how the output is checked, and the working manual.
-
Service & UX design
I design user journeys, operational flows and information architecture (IA).
-
Research & project operations
I define problems through research, then split scope, schedule and roles.
-
Communication
I create a service's visual language, along with explainer materials.

01 / 05
Problem Statement
Define who gets stuck, and in what situation, in a single sentence.
Rather than taking a brief at face value, I rewrite it as one problem statement covering the user, the context and the friction. I also set what is in and out of scope, so every later research and design decision is measured against the same line.
02 / 05
Research & Insight
Separate verified facts from hypotheses, so research can support decisions.
I document findings from user interviews, literature and reference analysis together with their sources. Recurring behaviours and pain points are clustered into insights, and anything still unverified is flagged as a hypothesis to test in the next stage.
03 / 05
Design Opportunity
Choose the opportunities worth pursuing, and design the flow before the screens.
From the insights, I select the points with the most user value and feasibility and frame them as design opportunities. Journey maps and service blueprints set the order in which people, operations and systems connect, and information architecture defines how the screens link together.
04 / 05
Prototyping
Turn the key flow into screens people can click through and test.
I build the most important flow first, in Figma and in code, and use it hands-on to find where people get stuck. The visual language and component rules set along the way are organised into a design system, so the product can grow without losing consistency.
05 / 05
Critique & Loop
Review against agreed criteria, and feed the results into the next revision.
I review the outcome for usability, accessibility and feasibility, then get a second look from outside the work. Issues go back to the stage they came from, and every changed decision is recorded with its reason, setting the baseline for the next project.
