Available to hire
I’m Dennis Nguyen, a UX/UI designer based in Santa Ana, California, focused on building clear, user-centered experiences for real products. I lead day-to-day design work in small cross-functional teams, collaborate closely with founders and engineers, and own end-to-end UX/UI across core experiences like profiles, events, bookings, messaging, and notifications.
I’m especially drawn to design systems, scalable workflows, and turning complex requirements into responsive, edge-case-aware interfaces. Through research and rapid prototyping—often using AI tools like ChatGPT, Claude, and Gemini—I explore journeys, compare directions, and deliver sprint-ready work with thoughtful acceptance criteria and developer handoffs.
