E-Commerce App Development

I'm looking for an experienced app developer to create an e-commerce application similar to JioMart or Blinkit. The app should be designed for both iOS and Android platforms and must include the following core functionalities: - Order and payment processing: The app should have a seamless and secure order and payment processing system. - Delivery tracking: The app must include a real-time delivery tracking feature. In addition to these functionalities, I also require the app to have user authentication features. Specifically: - Both email and social media login: Users should be able to authenticate themselves using both an email and password as well as via social media platforms. Ideal candidates for this project should have a strong background in e-commerce app development, with a portfolio that includes apps with similar functionalities. Experience with implementing secure payment systems and real-time tracking features is highly desirable. Excellent skills in cross-platform app development and user authentication systems are also essential.
