UX / UI Designer · Problem framing before pixels

The gap between what a product does and what users actually need is where the design work lives. I frame it, map the trade-offs, and build the simplest thing that closes it — sometimes by removing features, not adding them.

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. The hardest call is usually knowing what not to build. I've cut working features mid-project because they contradicted the brief — and the case studies are honest about those moments.

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.
