[ Evidence, not guesses ]

A product designer who doesn't guess.

I research how people build trust with AI — then design the products that earn it. Research-led, evidence-first, shipped.

[ How I work ]

From question to evidence

Most design work starts with a solution. Mine starts with a question I can actually answer. Four stages, each producing something you can act on — not a deck, a decision.

Research session in progress
[ Research in progress — paper before pixels ]
01

Discover

[ Where the question forms ]

  • User interviews
  • Field research
  • Competitive teardown
  • Trust & risk mapping

I start with your users and the thing you are actually unsure about. No pixels until the question is sharp.

02

Define

[ Where the noise drops out ]

  • Synthesis & coding
  • Information architecture
  • Personas & journeys
  • Design brief

Interviews get coded, patterns get named. You leave with a written brief and an architecture, not a mood board.

03

Design

[ Where form meets evidence ]

  • UI & interaction design
  • Design systems
  • Prototypes in 48h
  • WCAG accessibility

High-fidelity screens and a system that scales. Every decision traceable to something a user said.

04

Validate

[ Where launch is the start ]

  • Usability testing
  • Task success metrics
  • Iteration rounds
  • Handoff & QA

Tested with real people, measured against the task. If it does not move the number, it goes back.

[ Case studies ]

Selected work

Coded and synthesised 40+ visitor interviews from the public evaluation of a heritage RAG virtual expert — finding that confident hallucination, not capability, was the real trust threat.

[ Outcomes ]

Numbers, not adjectives

Measured results from shipped and evaluated work. Where a figure comes from a concept study rather than production, the case study says so.

[ Research background ]

Where others guess, I have evidence.

I spent time in academia studying the exact problems AI product teams are now shipping into. That background is not a detour — it is the differentiator.

Most designers cannot walk into an AI startup and talk about how users build trust with a model that sometimes invents things. I can, because I studied it in the field.

[ About ]

Detour through research. Back with evidence.

I am a product designer with a research background in AI trust and human-computer interaction. I have shipped across SaaS, e-commerce, smart cities and accessibility — always with measurable outcomes.

I use AI tools to move fast, but the judgment about what to build and why is still mine.
