I will create, deploy, fix, update website, api with python, flask

Hi, left you messages in regards to the Gig, I will create, deploy, fix, update website, api with python, flask: Can you help me with an existing PYTHON app that pulls data from my Amazon Play Books account and generates an Excel table. Until recently. I'm getting aborts at the end of this process and it's not generating the Excel file. Currently this app uses an internal server http://127.0.0.1:5000/ but the Python doc says I should use a WSGI server for production. I have well over 10,000 books in my ebook library and I suspect that this is more than the internal server can handle?
