A Small Selection of Personal Projects

The site is hosted on Azure Web Services as a containerized application (Docker). I am currently adding the ability for readers to leave comments on pages. This feature is implemented as a RESTful web service hosted on Azure (containerized), with the comments stored in an Azure SQL Server database. I am extending the site engine to retrieve and display comments as well as accept new comments, and I am making a separate application to notify me of new comments so that I can approve or reject them.
