The objective is to build a minimally featured end-to-end system. Users can sign up, create an account, pay, and access the core technology that is hosted on the cloud. The core technology is a separate component that is not part of this discussion.
Specifically, this pertains to the website and everything that goes on behind the scenes during a user interaction.
Key considerations: this needs to scale, be reasonably quick to implement, and secure so someone else can take over at some point. Also assume that UI/UX design is ready. I expect that this will take time, which is fine.
I'm going to start this discussion with the first steps:
1) WP to get the front end up: 1-2 days 2) Flush out landing page: 3 days
Right away I know I'll need one or more of php/js/jquery and mySQL, and integrate with payment processors and gateways.
Thoughts, best practices?
