Cubus | Real Estate Investment Manager
A real estate management application based on ASP.NET MVC. My responsibilities included developing both the back end and front end of the application. I integrated it with an SQL Server database using Entity Framework and deployed it on AWS using TeamCity.
The application was integrated with external services to provide financial metrics for comparing the value growth of real estate investments with the growth of other rates over the same period for reference. It allows data visualization through various charts and offers reports on new property valuations via a dynamic web interface.
