I have just pushed my latest project live for the group ST220 ENTHUSIASTS.
It is a mobile friendly Umbraco CMS based website, the front end has been written using Bootstrap, jQuery, Now UI, AJAX and the Razor template engine.
The underlying code is the Umbraco CMS system which runs on Dot Net Framework 4.7 (C#).
Some of the code i used in the site has come from a really useful resource codeshare.co.uk
