Reverse engineering the QR code generator and URL forwarder... with Mariatta
summary
Builds a local QR generator and URL forwarder using Python and the qrcode library, a one‑page Django app, Postgres for slugs, and static assets on DigitalOcean, deployed to Heroku; QR images render client-side with no ads or URL masking and redirect works when scanned. Adds a simple visit counter (one field increment on redirect) and an admin UI to swap targets, so printed banners stay valid without reprinting. Code is small, pragmatic, and functional.
