Approach to design

  • Ownership

    I deeply care about the success of the products I build and the people I work with.

  • Development

    Having experience writing code, I am capable to bridge the gap between design and development.

  • Strategic

    I make sure the major creative decisions actually solve user problems and contribute to a business goal.

  • Systems Thinking

    I think in systems, not just screens. By building through components and patterns, I ensure every product stays consistent and is easy to maintain.

  • Accessibility

    My goal is to make sure every UI is usable by as many people as possible. I believe that when a product is accessible, it’s a more open and intuitive experience for everybody.
