Fill xfa PDF form with json format data using itext or similar programs

My project is to fill an xfa PDF form with data in the JSON format. I will use programs like itext to accomplish this task- it is important for me to find a freelancer with a good knowledge of programming in this field. The data that needs to be filled in the PDF form is in XML format. I have a specific template for the PDF form.
I need a program that can batch fill json or csv format data to a pdf with fillable forms, which is a xfa format. Please find attached. or (https://www.uspto.gov/sites/default/files/patents/process/file/efs/guidance/updated_IDS.pdf)

Json file, for example, would look like the following. There can be more than, for example, one data in “us_patents”. In such a case, the table should add a new row as if “add” button is clicked, which will add a second row with cite no. 2.

After the data is filled in the pdf forms, I want the pdf file to be saved without flattening it. Therefore, the pdf file should still be editable after the data are all entered.

Also, please consider that this program will be run on a server when a customer sends a request. So, this program should be implementable for a web-service.
