Designer by trade.

Illustrated portrait of Milton Cantellay

Hi, I'm Milton.

I’m a product designer in the Greater Seattle area. I help teams make complicated products easier to use, from consumer rewards apps to enterprise workflows.

My background spans product design, branding, web, and motion. I care about how things look and feel, and whether they make sense to the person using them. A cleaner screen isn’t much of a win if people can’t find what they need.

These days, I’m leaning into AI as part of my workflow and learning by building. Neighbr.ly and my game projects give me room to explore what these tools can do, where they fall short, and how to guide the results. I bring the design experience; I’m still learning the development side.

I want to work with good people who care about the people they’re designing for. I like making things together, questioning assumptions, and arriving at work we can be proud of. I’ll advocate for the user, even when the simpler answer is less exciting in a presentation.

Outside the browser: learning guitar, mostly to the dismay of my family and our dog.
