Overview
ShopQR lets local merchants launch a mobile-optimized catalog in minutes. Each shop gets a branded QR code and a shareable catalog, and customers order over WhatsApp. It has Free and Pro tiers.
The problem
Local merchants need a mobile-friendly catalog and a simple way to take orders, without building a website from scratch.
What I built
A catalog builder with a branded QR code, shareable catalog, WhatsApp ordering and AI-written product descriptions using the Gemini API.
Key features
- Catalog builder with a branded QR code and a shareable catalog link
- WhatsApp ordering with structured, pre-filled order messages
- AI-written product descriptions using the Gemini API
- Analytics tracking and customizable themes
- Security: bcrypt (cost 12), JWT sessions, a 5-attempt brute-force lockout, IP-based rate limiting and owner-scoped authorization
Result
Lighthouse 100/100/100/100 on desktop and 95 performance on mobile. 120 active shop merchants.
What I would improve next
Add multi-language support for WhatsApp menus.
