Hello,
Will you please provide the first version of the wireframe and also a working prototype of the application?
Being a C# developer (for more than 5 years) and currently switched to developing web applications, preferably using the MERN stack along with some AWS services, such as Cognito, DynamoDB, EC2, and others, I would like to go through the detailed requirements of the project and see if I can help you with the same.
Regards.
