Modern React Native UI Design

I’m building a new React Native application and need a designer who can create a professional, sleek interface that instantly feels contemporary. I want the visuals to switch gracefully between dark and light themes, so users can select the mode that best suits them without any loss of clarity or brand consistency.

Here’s what I’m after: polished screen layouts, intuitive navigation patterns, and a cohesive component library (buttons, cards, forms, icons) that will translate smoothly into React Native code. Every element should look just as sharp in either theme, with typography, spacing, and color accents carefully balanced to maintain a clean, premium feel.

Please deliver:

• High-fidelity mock-ups for all core screens in both dark and light modes
• A comprehensive style guide detailing colors, typography, and component states
• Exportable assets (SVG/PNG) plus any relevant design files (Figma, Sketch, or Adobe XD)

If you’ve crafted mixed-mode mobile designs before, especially for React Native, I’d love to see them. Once approved, these designs will go straight to our development team for implementation, so clarity and component consistency are key.
