The Certification-System is built using ASP.NET Core and Razor Pages. Application data is stored in a non-relational MongoDB database, and access to this data is done using the MongoDB Driver.

User authentication and authorization is provided by ASP.NET Core Identity along with a provider that allows the MongoDB database to be used as a data store. The Bootstrap framework was used to style the UI.
