Hi there!
I've been working with mobile apps for more than 3 years and have built apps in areas ranging from ecommerce, elearning, retail, enterprise crm, to name a few. With that level of experience, I believe that I can definitely get you what you're looking for, if not better. A plus point is that I've recently worked on an ecommerce app for IOS which works in a similar fashion, has the ability for social logins(Facebook, Gmail and wechat), push notifications, promotion emails and many more.
On working with me, you'll be getting clean code, rich, user centered UI and a seamless performance in your app. Let me know if you have any questions and we can start working right away.
Thanks
Anmol
