Created in one weekend, as a case study in business automations. The QR Shop features over one hundred customizable QR codes.
Gumroad.com and a Raspberry Pi 5 handle order fulfillment workflows. Assets were created en masse with Wolfram Language 14.1.
In order to scale up to +1000 products, incorporate WordPress/DirectAdmin APIs for online asset management (AdminAutomated.com side). As batch-uploading is not available in the Gumroad API (atm?) consider browser-level RPA for product uploading.
