I made an entire e-commerce platform on Shiny

" summary

The project builds ggirl, an R package that turns ggplot2 plots into physical postcards via a ggpostcard() call that POSTs images to a Shiny backend, triggers a Stripe checkout, and uses external printing APIs. It uses brochure to let Shiny listen for POST/webhook requests, callr to spawn background R processes so Stripe gets immediate confirmations, and blastula plus image resizing for emails. Production runs on Saturn Cloud, shipping takes ~1–2 weeks and finding a high‑quality printer proved surprisingly time consuming.
