Paytm

In this project I have meticulously crafted a web application that mimics the functionality of leading digital payment platforms. By leveraging cutting-edge technologies and best practices I have created a seamless user experience for managing transactions and interactions within the app.

🧐 Features

Here're some of the project's best features:

• Users can create accounts transfer funds to their app wallet and send money to other users. The system ensures transaction integrity through database transactions mirroring the reliability of bank transactions. Successful transfers credit the recipient and debit the sender while any errors result in a rollback to maintain data consistency.

• By combining these technologies and functionalities my project aims to deliver a robust scalable and secure digital payment solution that provides a seamless experience for users.
