I built XeroxQ in 3 days - a QR queue system for India's chaotic print shops. Here's the whole story.Every college student in India knows this pain.You walk into your local Xerox shop 10 minutes before class. There are 6 people ahead of you. No token system. No order. Just whoever shouts loudest gets served first.You miss your class. Your file doesn't get printed. This happens every single day across millions of print shops in India.I decided to fix it.---🔧 WHAT I BUILTXeroxQ is a QR-based queue management PWA for local print shops.Here's the full flow:→ Shop owner gets a unique QR code (one time setup, takes 2 minutes)→ Customer scans QR, uploads their file, gets a token number→ Shopkeeper gets a WhatsApp message with a view-only link to the file→ Files auto-delete after 2 hours (privacy first 🔒)→ Zero app install on either side — pure browser PWAThe key insight: the shopkeeper does ZERO onboarding. The QR code does all the work. That's the only reason this can actually spread.---⚙️ HOW I BUILT IT (THE STACK)- Flutter (PWA) — frontend, works on any phone browser- Supabase — auth, database, file storage, Edge Functions- WhatsApp Business API — shopkeeper notifications- Token generation logic — Edge Function on SupabaseTotal build time: 3 daysTotal infra cost: ~$0
