"CFP Exchange tries to gather current Call For Papers from events around the world by crowd-sourcing them from the community and provide you with all the tech events at one single place. You can even upload events yourself. The site is built with asp.net core 2.0 and entity framework core 2.0. It's backed by a MSSQL database. Everything runs on Azure. Deployment is handled using ARM templates and VSTS (Public Projects). Connection strings are stored in a Azure Keyvault and we created an Azure Function to fetch the event image so we're not dependent on the remote image hosting. Communication between the app and the function is managed using Azure Service Bus."
