I am interested. Do you have some wireframe/mockup ready?
I am a professional software developer for more than twenty years, focused only on iOS app development for more than a last five.
After working on my last job, I quit and started working as a freelancer. So, five years later, I have two respectable careers on Freelancer.com and Upwork.com.
My focus last five years is strict to iOS frontend applications. During that time I worked with my clients from all around the world: USA, Australia, Deutschland, Italy, France, United Arab Emirates, Greek, China and more of them. They rated me with the best scores in over 60 projects and 750 billed hours combined.
During last year and so, my focus is on Swift apps which form the majority of my jobs.
