Consultant developer for a social media application

I'm looking for an experienced consultant developer to join my project and help create a unique social media application for both iOS and Android. The main purpose of the application will be focused on photo and video sharing, and will also have other features like messaging, content creation, and more. I have a specific vision in mind for my application and am looking for someone who can work with me to bring it to life. I am open to suggestions for additional features and design elements, but I expect my consultant developer to have a good understanding of what is needed for the application to meet my expectations.
