For the Polygraf.ai app, I took a mobile-first approach, designing an experience that feels seamless on phones while scaling smoothly to tablets and desktops. The interface was built to support both dark and light modes, ensuring accessibility and a consistent experience across user preferences. Every screen was crafted with responsive layouts and adaptive components, allowing the product to look and function beautifully on any device or screen size. The result is a flexible, modern design system that keeps usability at the core while maintaining a sleek, professional aesthetic.
