QR Codico - QR Code Generator Web App

What's QR Codico?

QR Codico is a lightweight web application I built to quickly generate QR codes in a clean, simple, and user-friendly way. The goal of this project was to create a fast, modern tool that allows users to generate QR codes without unnecessary steps, ads, or distractions.

Project Purpose

The main purpose of QR Codico is simplicity. Many QR generators online are overloaded with features, popups, and restrictions. I wanted to build a tool that focuses on one thing and does it well: generate QR codes instantly.

This project also served as a practical example of how a small, focused web application can still be well-designed, performant, and user-oriented.

Key Features

• Instant QR code generation
• Clean and minimal user interface
• No registration or login required
• Fast loading and responsive design
• Works across desktop and mobile devices

Design & User Experience

The design is intentionally minimal. I avoided unnecessary visual noise so users can focus entirely on the task. The interface guides the user naturally enter the data, generate the QR code, and use it immediately.

Responsiveness was an important part of the project. The application adapts smoothly to different screen sizes, ensuring a consistent experience on mobile, tablet, and desktop devices.

Technology Stack

QR Codico was built using modern web technologies with performance and maintainability in mind.

• Frontend: HTML, CSS, JavaScript
• Framework: Next.js
• Deployment: Vercel
• QR generation: JavaScript-based QR libraries

Using Next.js allowed me to optimize performance, simplify deployment, and maintain a clean project structure.

Development Approach

I approached this project with a “less is more” mindset. Instead of adding features just to make the app look complex, I focused on:

• clear functionality
• fast response time
• simple logic
• clean and readable code

Because I worked on this project alone, every part, from design decisions to implementation was handled personally. This gave me full control over quality and consistency.

Challenges & Solutions

One of the main challenges was keeping the app extremely simple while still polished. It’s easy to add features; it’s harder to decide what not to include.

I solved this by continuously testing the app from a user’s perspective and removing anything that didn’t directly improve usability.

What This Project Demonstrates

• Ability to build focused, purpose-driven web applications
• Strong understanding of UI/UX principles
• Clean frontend architecture
• Efficient use of modern frameworks
• Solo project planning and execution

Conclusion

QR Codico is a simple but effective tool that demonstrates my approach to web development: clarity, performance, and purpose-driven design.

It’s a small project, but it reflects how I think about user experience and clean implementation — whether I’m building a simple tool or a full-scale website.
