Tamrah is a digital loyalty platform built for specialty coffee shops in Saudi Arabia — replacing paper punch cards with NFC-tap Google Wallet passes. Customers join in one tap, no app required. I designed and built the full stack: bilingual Arabic/English landing page, merchant dashboard, customer join flow, NFC stamping, and Google Wallet pass issuance with signed JWT loyaltyClass objects. Stack: React + TanStack Router, TypeScript, Supabase , Google Wallet API, Cloud Run. Delivered: premium brand system (amber/cream palette), scrollytelling landing, end-to-end loyalty issuance
