What is a design prototyper?

A Design Prototyper is a professional who creates interactive models or mockups of digital products, such as websites or mobile apps, to visualize and test design concepts before development begins. They work closely with designers, engineers, and product managers to translate ideas into tangible prototypes that demonstrate user flows, functionality, and visual elements. This role helps teams gather feedback, identify usability issues, and iterate on designs more efficiently, ultimately speeding up the product development process and improving user experience.
