One of my longest and most complete projects was a WYSIWYG (What you see is what you get) website editor for a software CRM that hired me.
This editor was much like WIX.com or some of the more modern website editors out there but it was years ago before everyone did it.
Beyond just a page editor the application allowed multipage websites, single squeeze pages, and interactive forms with custom fields.

• Created WYSIWYG website publisher with Net MVC that integrated with an in-house Umbraco CMS. This allowed customers to publish multi page websites and single squeeze pages. This project required a good deal of front-end knowledge such as the document object model (DOM), cascading style sheets (CSS), and JavaScript/JQuery.
• Utilized free Javascript project CKEditor (https://ckeditor.com/) to handle the user interface and custom editor toolbars.
• Wrote console applications in C# to manage integration between CMS and in-house website publisher application. Included many business tasks such as blanket data updates, customer data export, and maintenance of bulk data.
• Integrated flagship CRM product into the website CMS by creating SOAP web services and getting the app to talk between the two products.
• Was also in charge of testing and QA tested all developed code myself. Utilized Redgate SQL Compare and SQL Data Compare to ensure database consistency between moving dev, QA, and production environments.
