RESTful API Development in C#

I'm seeking an experienced C# developer to port a python webapp app to a C# web app (most likely ASP .NET with RazorPages).

There is no database, all the data comes from an existing API.


Key Skills & Experience Required:
- understanding the fastapi + jinja templates (python based)
- Hands-on experience in developing RESTful APIs using C#
- simple and clean code
- data serialisation

The entire app has 100 lines of code + ca 100 lines of HTML template
There are 3 buttons and about 6 endpoints

Task:
GIVEN: A simple webapp in python (fastapi + jinja)
RESULT:
- A webapp with the same functionality based on C#
- it should be easy to understand / clean code
- data serialisation as in the python app / template
- short documentation (dependencies/install/deploy)

Only apply if you actually know both frameworks.
