A bit about me

I’m a Digital Product Designer dedicated to function, accessibility, and thoughtful craftsmanship. Over the past eight years, I’ve designed web products for a healthcare communication scale-up and two UK government departments, helping essential services to run more effectively. With each project, I aim to make the web a little more useful and human-centred.

  • UX, UI & web design
  • Prototyping
  • Usability testing
  • Developing design systems
