Ecommerce App Development

I am in need of someone to develop an Ecommerce App for me. The app should be developed to run on both iOS and Android platforms. I have some ideas of the design and layout of the app but I am open to suggestions. In terms of features, the app should include basic features such as a product listing, shopping cart, and payment processing. It would also be great to have some more advanced features such as user profiles, social media integration, and push notifications. If you have any creative ideas on how to best optimize the performance of this app, I welcome your suggestions. If you are available and have the expertise to bring my vision to life, I look forward to hearing from you soon.
