IoT & AI Platform UI/UX

I am building a Commerce-focused University IoT & AI system intended for commercial roll-out, and I need a complete UI/UX design that feels effortless on both mobile phones and full-size desktop browsers. The platform will stream live sensor data, surface AI-driven insights, and serve multiple user roles ranging from students to facility managers to external partners, so clarity and consistency across breakpoints is essential. Key features the interface must cover: • Data visualization that can handle real-time charts, graphs, and heat maps. • Robust user authentication with clear role-based permissions. • Interactive dashboards that each user can personalise and save. Here’s what I’d like from you: wireframes that map every major user flow, high-fidelity mock-ups, and a clickable prototype (Figma or Adobe XD preferred) so stakeholders can experience the journey end-to-end. Please include a basic style guide—type ramp, colour palette, iconography—and hand off neatly layered design files ready for development. The final designs must be responsive, touch-friendly, and meet WCAG 2.1 AA accessibility guidelines. If you have experience designing for real-time data products or AI-driven interfaces, tell me how you tackled performance and clarity. I’m happy to answer any domain-specific questions once you’ve reviewed the brief.
