HelpSBIsupport at Freelancing client

I developed a Flutter application for a freelancing client that offers a seamless user experience. Users can authenticate themselves securely, providing the necessary details. They have the flexibility to set up payment methods, including both credit and debit cards, while selecting their preferred plans. To enhance security and ease of use, we integrated Firebase's phone authentication system for OTP verification. All user data is securely stored, and a copy is sent to the admin via email, ensuring a smooth and efficient process for both users and administrators and also website from where this app can be accessed and admin can get all details of user security
