Successfully redesigned and implemented a user-centric interface for FollowG's B2B app, leading to a remarkable 15% increase in task success rates and a dramatic 60% reduction in errors. Through comprehensive user research, competitor analysis, and heuristic evaluations, We gained invaluable insights that informed my designs. We then crafted both low- and high-fidelity wireframes, along with sophisticated responsive prototypes tailored specifically for electronics retailers. To ensure a cohesive user experience, we established a robust design system, developed a versatile component library, and created clear UI guidelines, all of which contribute to a consistent and compelling product.
