Solution and Project Value

QReel offers the option for users to get digital receipts for every transaction in the store and record every transaction in the application so that users can manage their expenses. In addition, QReel directly reduces the carbon footprint by reducing the use of paper waste.

  • Reducing paper waste produced from stores
  • Avoid BPA (Bisphenol-A) exposure on shopping receipt
  • Create monthly budgeting plan

Technology Highlights

We store our users' data using PolarDB for PostgreSQL. This service option was chosen because our team uses PostgreSQL for the database. PolarDB for PostgreSQL provides an easy-to-use management interface, making it easier for us to manage and monitor their database.

We use Alibaba Cloud ECS service to deploy REST API applications. Alibaba Cloud ECS can easily increase or decrease resource capacity according to user requirements. This makes it very easy to deal with traffic spikes or high usage on applications.
