About me

A little about how I approach the work.

Working across different teams and industries has shaped how I build. I like understanding who a product is for and how its pieces fit together, from the interface to the engineering behind it.

  1. Start with the person.

    I consider accessibility and clarity from the start, so people can understand and use what I build.

  2. Design for the whole experience.

    I think about how the interface and the engineering behind it work together, and what those choices mean for the person using it.
