Integrate Python Backend with Frontend

I need a skilled developer to link my completed frontend with a Python backend. The task involves: - Pushing real-time data from the frontend to the backend. - Fetching data from the backend to display on the frontend. I prefer using REST API with polling for real-time data communication. The backend's response format is XML, so familiarity with handling XML responses is crucial. Ideal candidates should have: - Proficiency in Python and JavaScript. - Experience with REST API and real-time data handling. - Skills in XML parsing and manipulation.
