UI/UX Design for my startup

I need a creative UI/UX specialist to craft a clean, modern, feminine interface for both a mobile app and its accompanying web platform—starting entirely from a blank canvas.

Core screens must showcase:
• A clear, intuitive navigation menu
• A visually appealing user-profile section
• Eye-catching yet unobtrusive interactive buttons
There is much more about this app lot of elements and features will be discussed further.

I already have brand colors ready to share, so every component should be harmonized with that palette. Beyond colors, I’m open to fresh ideas for layout, typography, iconography, and subtle micro-interactions that elevate the overall feel.

Scope of work
1. Establish a concise style guide (fonts, spacing, icon style, button states).
2. Produce pixel-perfect high-fidelity mock-ups for key mobile and web screens.
3. Create an interactive prototype (Figma, Sketch, or Adobe XD) so flows can be reviewed in real time.
4. Supply organized source files and exportable UI assets for hand-off to developers.

I’ll provide further feature details, existing brand files, and a brief on user personas once we start. Looking forward to seeing how you blend elegance with usability across both platforms.
