A smart, QR-based email automation tool I built to streamline personalized communication. It allows users to generate QR codes linked to dynamic email templates containing variables in the subject and body. When someone scans the QR code, they're prompted to fill out a form, and their responses are used to replace the placeholders. The user is then redirected to their email app with a prefilled, ready-to-send message. The system includes a real-time dashboard to monitor scans and submissions, built using Socket.io. The full-stack architecture is powered by React, Node.js/Express, Supabase for authentication and database, and Upstash Redis for fast, session-aware processing. Email delivery is securely handled via SMTP integration through Render.
