Project on hold 🔒

The project is currently on hold. The main goal to experiment with the tech stack has been satisfied.

Stamp

Stamp is a loyalty stamp-collecting app designed for café enthusiasts.

Why?

The primary motivation for this project is to experiment with Scala stack.

This project is not production ready. I use it to learn and experiment with different technologies and approaches.

Tech Stack

  • Scala 2.13
  • Tapir
  • Cats and Cats Effect
  • Refined types
  • Doobie
  • Postgres
  • Circe
  • Pureconfig
  • Chimney
  • Embedded Postgres (based on bootzooka)

Usage

Restaurant Employees and Owners

Restaurant owners and managers can configure stamp settings and establish the rewards that customers can earn. Additionally, they can authorize specific employees to scan visitors' QR codes for both stamp collection and reward redemption.

Café Clients

Every time you visit your favorite café and make a purchase, you have the option to show a QR code and earn a stamp. Accumulate enough stamps and you'll unlock rewards.
