Mobile App UI/UX Designer Wanted

I'm currently searching for an experienced user interface/user experience designer that's capable of creating the look and feel for an e-commerce mobile application. While the specific type of the app isn't determined yet, your wealth of experience will still be a definite asset to bring compelling visuals to life. Experiences with both Android and iOS applications are beneficial.

The key requirements include:
- Strong portfolio displaying a variety of UI/UX designs for mobile devices
- Proven understanding of UX principles and ability to apply them in designs
- Understanding of design tools such as Sketch, Adobe XD, Figma

To apply for this project, make sure you:
- Share your previous experiences and designs.
- Indicate your level of proficiency within each of the aforementioned design tools.
- Showcase your proficiency to translate user needs and constraints into compelling designs.

While I have skipped the specifics on style or design elements, a general flair for beautiful, clear, and intuitive interfaces across devices is greatly appreciated.
