There is an informative website on google sites, of a workshop.
It is required to show according to the assistant certain unique information that is his qualification.
The workshop has 3 workshops, each workshop will have 5 courses and each course will have a percentage rating. This information that could be an excel upload to the DB that is created (firebase, etc etc) and when a participant accesses the web on google site, you should only see their qualifications and when you click on a course, it will be like a hyperlink to the course page on google site with all your information.
The excel could be a Google Data, where it is updated directly. The data could be: email gmail assistant, workshop code, course name, value. The idea is to be shown as a board.
If you have an example of this type of solutions on google sites as if it were intranet or training portals it would be great. Send link to see it.
