Project History
Enocta: End-to-end Digital Learning Solutions
There are various platforms, web browsers, mobile applications, Microsoft Office extensions to upload powerpoints, FTP daily folder employee integrations, web service integrations, and single sign-on and SMS integrations.
I was the back-end solution architect, senior developer, and DBA for cloud clients, and the DevOps engineer for on-premises clients.
This solution had a hybrid web application (inside a web form, there was a single page that included React coding) with the course catalog pages using ASP.NET MVC. Some administrator pages were ASP.NET web forms. There were two mobile apps besides web applications: Android and iOS. I coded and architected the back-end web API portion. The same web API responded to React pages for the web app. There were two web services for client integrations (SOAP services), SQL jobs (calling stored procedures), night jobs, and C# Windows service.
