Front End
The front end of this website is designed to answer visitors questions about the product and then to direct them to download the app.
Back End
This app also has a PHP backend which is the interface to the product's item and customer data.
Item data consists of images and text about the items users want to sell. An unlimited
number of pictures could be added for each item. It also includes user authentication and
maintenance, including adding new users to changing passwords, setting site permissions.
Note: Since the backend was for internal use only it was not styled to save time and keep
it simple.

Server to Phone SMS Messaging
This server includes an elaborate system for communicating directly from the website to
users via SMS messages. If the carrier was unknown or partially known then SMS messages
would be sent to all carriers in the area with any that bounced back being examined and
eliminated from the list. Finally when only one carrier remains then that carrier is
saved as a user's carrier. This system was robust enough to stop the process if the user
returned a message as in that case the user message can be interrogated to determine the
carrier.
This solution was developed from scratch using straight PHP on a LAMP stack.
