This is the QRCode Service (Kotlin) project I made myself.

This project utilizes QR codes — 2D barcodes that can store large amounts of data and are easily read by smartphones. Through this Spring Boot project, users can learn about the technology behind QR codes, generate them programmatically, and integrate them into a web service.

Here's the link to the project: https://hyperskill.org/projects/414
