Create [url removed, login to view] script (server-side) that produce PDF report with text and image received from database, the file should then be saved into the same record. Use pg-promise for database connection. The sample/test database is ready for use. Attaced is my documentation for the database and report. PDFKit is recommended to use, maybe you have a better solution?
How are you. I've full experiences for node.js, express, postgre and pdfkit. I can fully help you, thus my budget is too high than your post price. I guess we can discuss more detail. Thanks.
