Scope of work

We took over the development of Stempli from a previous vendor — a fully digital loyalty program that replaces paper stamp cards with a mobile app. We cleaned up the existing codebase, delivered new features, and carried out a comprehensive UI/UX redesign to align the product with modern trends. Customers of restaurants, beauty salons, and shops collect stamps by tapping an NFC card or scanning a QR code, while owners manage the program from a web dashboard.

Features

  • Project takeover — a smooth handover of the code and infrastructure from the previous vendor, with no service downtime.
  • UI/UX redesign — a refreshed, modern mobile app interface aligned with current trends.
  • Digital stamps — collected via NFC tap or QR code scan, no paper cards.
  • Configurable rewards — business owners set their own stamp thresholds and reward types.
  • Push notifications — automated marketing messages and promotions with no manual sending.
  • Analytics dashboard — real-time statistics on stamps collected and rewards redeemed.
