Qroq — QR Code Generator
Overview
Qroq is a full-stack QR code generation platform designed to make creating and customizing QR codes simple and reliable. The application supports both static and dynamic QR codes, along with customization options and built-in QR code scannability validation.
The Challenge
Creating a QR code is easy, but ensuring that a customized QR code remains reliably scannable can be challenging. The project required a system that could generate different types of QR codes while allowing users to customize their appearance without compromising readability.
Solution
I developed Qroq as a full-stack web application with a dedicated QR generation and validation workflow.
Key features include:
- Static and dynamic QR code generation
- QR code customization and styling
- Border and margin customization
- QR code text and design settings
- Automated scannability validation
- Backend QR processing and validation
- Database integration for managing application data
- Responsive user interface
My Role
I worked on the application's frontend and backend development, including QR generation, customization components, validation logic, API integration, and database-related functionality.
One of the key parts of the implementation was integrating QR scanning libraries to verify whether generated QR codes remained readable after customization.
Technical Implementation
The application uses a modern full-stack architecture with React and Node.js/Express for the application layer and MySQL for database functionality.
For QR validation, libraries such as JSQR and QR Scanner were used to programmatically test generated QR codes and identify potential scannability issues.
Tech Stack
Frontend: React, JavaScript, HTML, CSS Backend: Node.js, Express.js Database: MySQL QR Technologies: JSQR, QR Scanner Tools: Git, npm
Outcome
Qroq provides a complete workflow for generating, customizing, and validating QR codes from a single platform. The project also gave me practical experience in combining frontend customization controls with backend processing and automated QR validation.
