Paypal Subscriptions

I am seeking a skilled PHP developer to implement four key functionalities into my website. The successful candidate will be responsible for integrating the PayPal Subscriptions and Payments APIs, as well as developing a partner scheme feature. This application will run within its own folder on the server, and all dependencies should be contained within this folder for easy deployment via FTP. Subscription Management: The developer will design and implement a subscription management system using the PayPal Subscriptions API. This system should allow restaurants to subscribe to specific plans, with billing occurring at regular intervals (e.g., monthly). It is important to ensure seamless integration with the PayPal API, handle subscription creation, billing, and cancellation processes. The system should direct all subscription funds to the web app owner's PayPal account. Tipping System: The developer will create a tipping system that allows customers to tip the restaurant for their orders. Each table will have its unique identifier, and customers will be able to enter a custom tip amount. The system should securely process the payment using the PayPal Payments API and distribute 80% of the tip funds to the restaurant's PayPal account associated with the specific table. The remaining 20% should go to the web app owner's PayPal account. Partner Scheme: The developer will implement a partner scheme feature that enables local businesses to advertise to the restaurant's customers. This feature should allow brand partners to purchase advertising space within the web app. The system should provide a user-friendly interface for brand partners to select advertising options and securely process payments using the PayPal Payments API. The system should distribute 80% of the payment to the restaurant's PayPal account, while the web app owner retains the remaining 20%. Bootstrap 5 Admin Section and Database: Additionally, a Bootstrap 5 admin section should be created within the application to allow easy management of successful payments, subscriptions, advertising partnerships, and ad hoc product creation for brand partners. The admin section should provide a user-friendly interface with features to view and analyze payment data, manage and cancel subscriptions, monitor advertising partnerships, and create custom advertising products for different brand partners and restaurants. A separate database should be created specifically for the admin section to store and manage relevant data. The successful candidate should have experience working with PayPal APIs, specifically Subscriptions and Payments. Proficiency in PHP, database management, Bootstrap 5, and dynamic product creation is required to ensure accurate tracking of transactions and the creation of an intuitive admin interface. Strong attention to detail, error handling, and data security is paramount. Please provide examples of previous work or projects that demonstrate your expertise in these areas, particularly in building admin sections, integrating payment APIs, and creating dynamic product systems.
