I need you to develop some software for me. I would like this software to be developed for Linux . Ruby web app. I need a ruby app that takes a JSON payload via a get parameter. it should be an array of ticket objects that will have various information. This information must then be fed into a ruby library called prawn. I need a new PDF page for each ticket passed through the GET parameter. I have a basic format setup through prawn, just need the HTTP server hooked up, and the ticket to be formatted with a QR code...I need this task done in 2 hours.
