Frontend for a modelling system

Project work in the design and development of a frontend for entering the data required to generate new power deals by means of a contract optimization model. The first version of the frontend is in Excel, subsequently the functionality is separated into a backend application built on ASP .net WebAPI with .NET Core and a thin client (Excel or a new web application). Data is exchanged using JSON with REST APIs and saved as a document in a CosmosDb instance. The backend passes the data to the central optimzation model. The whole environment is hosted on Azure. The project is organized using Scrum, whereby the Business users define the user stories to implement.
