I find the gap between what a product does and what users actually need. Then I close it, from research through prototype.

Spotify

Recently Played Controls

Spotify's highest-visibility surface offers no way to manage what appears there. I designed three shelf-native controls (Pin, Remove, and Pause) that give users agency without degrading the recommendation engine.

Design is a
decision problem.

Every project starts the same way: I look for the space between what users expect and what the product actually gives them. That gap is where the design work lives. I frame the problem, map the constraints, then build the simplest thing that closes it.

My work spans consumer apps, content platforms, and e-commerce. Beyond the interface, I care about the systems underneath: interaction patterns, information architecture, accessibility, and the handoff details that make or break implementation.

How I work

I start with the problem before opening Figma. Research shapes the brief. The brief shapes the structure. The structure shapes the interface. In that order. The decisions that matter most happen before the first frame.
