Portfolio of Lamont Hart

I design systems that teams build on.

I'm a product designer who builds at scale. I've shipped a design system used across 70+ Amazon tools, led UX for a global EHS platform in 50+ countries, and redesigned an AI content platform at American Express — all while keeping the work grounded in real user needs and systems that hold up over time.

A quick introduction and what drives my work.

Hello, I’m Lamont—a product designer focused on creating thoughtful, scalable digital experiences. My work sits at the intersection of user needs and business goals, where I design intuitive interfaces, build design systems, and turn complex workflows into simple, usable solutions.

I’ve collaborated closely with cross-functional teams to bring products to life, from early concepts to polished experiences. I enjoy blending research, strategy, and emerging tech like AI to improve how people interact with digital products, and I’m always looking for ways to make those experiences more meaningful and efficient.
