I need a UI UX design for my microtask website and app (cross-platform)

I'm looking for an expert UI/UX designer to create a cross-platform design for my microtask website and app. The design should be compatible with all platforms, including web, iOS, and Android. I'm open to any suggestions for design, with no specific design references or inspirations in mind. Additionally, it should be responsive and adaptable to different screen sizes. If you have the skills necessary to create a modern, attractive design that reflects the latest trends, I'd love to hear from you!
