New screens of UI from existing app

I am looking for someone to help me with my project needs. I need a freelance designer to create new screens of UI from an already existing app for personal use. The particular software that should be used is Figma. Ideally, the freelancer should have a solid understanding of user interface design practices, as well as experience working with Figma for prototype creation. I am open to working with any designer who works in a professional, timely, and reliable manner. Totally 15 screens need to be designed in very short time.
