Design System for AI Platform

I'm looking for a designer to help create the end-to-end design system for a SaaS platform currently in development. The scope includes defining the visual language, component library, design principles, interaction patterns, and scalable UX foundations across the entire product experience. The goal is to create a cohesive, intuitive, and high-quality interface that supports complex data visualization, actionable insights, and long-term product scalability. I'm looking for someone with experience designing comprehensive design systems for B2B SaaS products, dashboard-heavy applications, or analytics platforms. Experience with Figma, component-based thinking, responsive design, and creating systems that can evolve alongside product growth is highly valued.
