About me

Maddi Firminger reviewing product design sketches at a worktable
Designing through research, sketching, and iteration

Thoughtful products begin with paying attention.

Hi! I’m Maddi, a Minneapolis-based product designer with a background in UX research and a love of making things people enjoy using.

My work spans physical products, digital experiences, and community apparel. I enjoy talking with people, understanding what matters to them, and turning those insights into thoughtful designs. I’m equally interested in the details that bring an idea to life, from materials and prototyping to working with vendors.

Outside of design, you’ll usually find me testing out new cocktail recipes, listening to Bleachers on repeat, or getting a little better at mahjong!
