Build a web/API app to manage our subscribers (Subscribers Management System)

Subscriber Management System is a Web-API system that enables the client to subscribe and unsubscribe to its service by using SMS API. The requirements are to create a Subscriber Management system to manage the relationship between [login to view URL] and customers from mobile operators (mainly: [login to view URL]). Where they can subscribe or unsubscribe to [login to view URL] service by sending SMS message, also the Subscriber system should be able to manage payments collections and code verification. The subscription in the service may be weekly, monthly, and yearly. We need to build it to let the clients subscribe to the service by sending SMS to a certain number like (sub 1 to 9999 weekly subscriptions in the service, sub 29999 monthly subscriptions. etc. Then the system adds the subscriber to its database, and sends SMS back to the subscriber to confirm that subscription process is successful, the message contains URL to download or ready-made an app from the App store, on their device, and activation code to use it later in the install process. The Subscriber System daily searches its database about the subscribers who finishes their subscription, and notify these subscribers to renew the subscription, if the renew process successes the system renew the subscription, else change the subscriber to inactive subscriber. When the subscriber wants to cancel his subscription in certain service, he has to Call an API by sending SMS to the certain number (unsub 1 9999 to unsubscribe weekly subscription, unsub 2 9999 to unsubscribe monthly subscription, unsub 39999 to unsubscribe yearly subscription).etc. Then the Subscriber System searches about the subscriber in its database, cancels his subscription, and sends SMS back to the subscriber to tell his that the unsubscription process was successful. We need to Develop a web Application to do the following: • Containing a web API to: Subscribe to the service, unsubscribe, Collect payments, Send SMS messages. • Designing a web page to subscribe client manually. • Create a Dashboard to manage client subscription, Cancelation, and SMS history. • Ability to enable or disable clients subscription manually. [More in the attachment] Technical requirements: • We need to develop it using Django, Python,Bootstrap, MySQL. • We will provide the deployment services. • Using bootstrap for dashboard & internal pages. • The system should be highly secure with considering for parameters encryption and input validating. • All variable need to be placed on a setting file. • All related documents need to be submitted upon delivery If you think you are capable of, please submit: - Your bid & proposal, After reading it carefully - Previous work & achievement. - Sample of code you have written.
