ecommerce app

I'm looking for an experienced developer to help me build an ecommerce app for both iOS and Android platforms. This ecommerce app must be able to integrate with payment platforms, as well as store user data. I want the app to be able to handle multiple payment methods and securely store customer data. As such, I'm looking for someone who has the expertise and knowledge in working with mobile technology. The successful candidate should preferably have a history of developing similar apps for multiple platforms. I am open to discuss the project further if needed. Thank you for your time and I look forward to hearing from you.
