I’m Sam Diaz, a Lead UX/UI Designer with 15+ years of experience creating products that turn complexity into clarity. I’ve worked with startups, agencies, nonprofits, and government organizations to deliver user experiences that are both intuitive and scalable. My approach blends strategy, research, and design systems to make sure products not only look sharp but also work seamlessly for the people who use them.

I move ideas from concept to prototype quickly by combining human-centered design with modern AI-driven processes. Early explorations evolve into clickable flows and interactive previews that feel close to final. This allows teams to validate decisions sooner, align stakeholders faster, and launch with confidence.

Over the years I’ve delivered design systems, interfaces, and product experiences for organizations like the USDA, USAID, the U.S. Census Bureau, DOT, Creativo, and ProMedia Fire. Across industries, the goal is always the same: build digital products that are clear, efficient, and engaging.

If your team needs a high-impact product interface, a scalable design system, or a clear process for shipping great design, I can help make it happen.
