Rewi: Digital Loyalty & Customer Pass Platform
Dynamic QR passes, POS counter validation, and visit analytics without mobile app downloads.
Challenge
Merchants and hospitality venues need repeat customer engagement, but native apps face steep download friction and paper cards lack digital tracking.
Engineering intervention
Decoupled web-first TypeScript architecture with dynamic mobile browser QR passes, integration hooks for POS systems, and merchant management console.
What was implemented
Unique QR pass generation, rapid counter validation interface, configurable rewards engine, and structured visit telemetry without tracking sensitive PII.
Architecture & decisions
Astro, TypeScript, Node.js, PostgreSQL, and Docker on Google Cloud. Webhook-driven integration with fault-tolerant counter checkout flows.
