I have an existing Node.js portal for insurance PDF processing. The current PDF extraction logic in Node.js is not very accurate. So I have created a Python script (using PyMuPDF + OCR + OpenAI GPT) that extracts insurance policy fields much more accurately. I need a freelancer to: Integrate the Python extraction logic with my Node.js backend. Accurately receive the extracted JSON and save it. Maintain all existing portal features (file upload, subscription checks, database updates). Provide a working demo to verify extraction accuracy. Deliverable: A fully functional integration on live website where the Node.js portal uses the Python extraction logic seamlessly and accurately and to check if any other bugs in code and also let us know where and which file to change next time if we want to modify the logic
