C#: webserver with a rest api, that calls OpenAI API with a pre defined context plus question from user

I am looking for a skilled C# .net developer to create a webserver with a REST API that calls the OpenAI API with a question from the user. At first phase: Web server will provide a REST API and gets a json with 2 STRING fields: data : // holds the data for the contexts of the question: e.g: "history of football" user_question : // a question from the user: e.g: "who are the best players?" And will return the response from OpenAi We will use this: [login to view URL] (we will implement non-azure, i will provide you an OpenAI API key)
