Develop User interface for my Python+ R code

I am in need of a web-based interface for my Python+ R code that will allow users to input data and run the code. I am looking for a developer with experience in Django to create this interface. The main function of the interface will be to take input from the user and run the code. It should be simple and easy to use. The ideal developer should have experience in web development, Python+ R coding, and Django.
