What I do

UX/UI design skills

Research-led design across discovery, prototyping, and validation, tailored to complex domains where trust and clarity matter most.

  • User research

    Interviews, surveys, and affinity mapping to learn what users need. Findings become personas, journey maps, and clear reports.

    • Interviews
    • Surveys
    • Affinity mapping
    • Personas & journey maps
  • UI design

    Clean, accessible interfaces with clear hierarchy. From wireframes to high-fidelity screens developers can build from.

    • Wireframing
    • Visual design
    • Design systems
    • Prototyping
  • Co-design & facilitation

    Workshops that bring stakeholders and users into the process, so solutions match real workflows.

    • Co-design workshops
    • Stakeholder facilitation
    • Sketching sessions
    • Design critiques
  • Usability testing

    Structured testing from script to report. I run sessions, capture findings, and turn them into design improvements.

    • Moderation
    • Reporting
    • Iterative refinement

How I work

My design process

Structured, user-centred design from discovery to delivery. Built for teams that need evidence-backed decisions, not just polished screens.

Step 01

Discover

Understand the problem, business goals, and the people affected. Interviews, surveys, and stakeholder chats define what we are solving and why it matters.

Why work with me

4 reasons why

Research-led, not guess-led

I do not design from guesses. Decisions come from user evidence like interviews, testing, and real workflow context, especially in healthcare.

Collaborative by default

Co-design workshops and stakeholder input are central to my process. The best solutions come when the people closest to the problem help shape them.

Outcomes over deliverables

Personas, journey maps, and reports only matter if teams use them. I focus on artefacts that drive decisions, not documents that sit on a shelf.

Clear handoffs that cut rework

I document what developers and product teams need, covering states, flows, and the reasons behind them, so implementation moves faster with fewer surprises.
