A good product is felt before it’s explained.

I’m Arthur. Since 2009, I’ve been designing and building interfaces. UI is where a product’s quality becomes an experience for the people who use it.

Front-end and UI, Bordeaux

What I believe

  • Between design and code

    It’s my nature. Shared components and rules connect the two, so quality holds up as the product grows.

  • Start with the person

    Begin with what the user goes through on screen. What the technology makes easy comes after.

  • Details make the product

    Spacing, a loading state, a transition. That’s where it shows.

  • Leave room

    I’m obsessed with white space and padding.

  • Choices you stand behind

    Interfaces look alike, from Bootstrap to Tailwind to AI-generated UIs. They lack risk-taking, an editorial vision, a strong identity.

Projects

  • 2026duckSlides in markdown, live demos inside the slide, your phone as the remote. My presentation tool, open source.duck.tutur.devGitHub

Path
