Cross-Platform PDF Fetch & Print App

I'm seeking a proficient Python or nodeJS developer to construct a cross-platform desktop app for Windows, Mac, and Linux. The main functionality needed is to fetch and print PDFs from a given endpoint. The app should have a Graphical User Interface (GUI), thus requiring the developer to have: • Strong expertise in Python or nodeJS • Proficiency in developing GUI applications • Understanding and experience with cross-platform development • Knowledge of handling PDF files and printers • Familiarity with interacting with API calls We need the source code (on github) and pipelines setup to build windows EXEs as well as Linux binaries. The app has a preshared url and uuid that identifies the printer, and only one printer is setup per uuid. The uuid is used to fetch a list of IDs from the server: (url/gxweb/getPrinterItems?printer_secret_key=uuid) : [45, 46] which is then in turn used to fetch the PDF: (url/gxweb/getPrinterItem?printer_secret_key=uuid&printer_item=45) : pdf binary and then the item is marked as (url/gxweb/updatePrinterItem?printer_secret_key=uuid&printer_item=45&status=done) : true statuses available: 'scheduled' : in this state it will appear in the PrinterItems list 'fetched': interim state showing it was fetched (not necessarily needed) 'error': error state if printout failed 'done': success state if the print seems to have worked. Some screen maybe showing a log might be handy for debugging and being able to check if it is working, but I am open to design suggestions. In my mind this is a system tray app that runs on windows, mac and linux, and since the only package I could quickly find that allow pdf to printer is a nodejs package, I am thinking this is an electron app. If you want to use another tech stack just check in. We use python and javascript mostly, with a couple of small new items in rust... I would not want to deviate from our known tech unless there is a good reason.
