    • Fiscalization in a nutshell, is the receipts being approval by the government. The SDK of ATOL lets you fiscalize a receipt; however, it works only on the installed machine. I created a NuGet package that connects to the ATOL driver and fiscalize a receipt.
    • E-Receipt Web Portal. The aim of this project is to create a QR code instead of printing a receipt so that the waiting time would be reduced. I integrated the application with MonetPlus.
