Grocery Fruits & Vegetables E-commerce App

I'm looking to develop a cross-platform (iOS and Android) mobile application aimed at selling my grocery fruits and vegetables. The app should be intuitive, user-friendly, and fully functional to support a seamless online shopping experience.

Key Features and Requirements:

- User Registration/Login: The app should have a secure and straightforward user registration and login feature. It should ideally support social media login options for convenience.

- Payment Integration: The app should support multiple payment methods, specifically Credit/Debit Cards and Digital Wallets. It should have a secure payment gateway integration to ensure safe transactions.

Ideal Skills and Experience:
- Proven experience in developing e-commerce mobile applications.
- Proficiency in both iOS and Android app development.
- Strong understanding of secure user authentication and payment integration.
- Previous work with grocery or similar e-commerce apps will be a significant advantage.

Please include examples of your previous work in your proposal, specifically those relevant to e-commerce and cross-platform mobile applications.
