🚀 Just launched: QR Code Generator Pro A full-stack Python application that generates QR codes with PERMANENT file hosting. 🔧 Tech Stack: - Backend: Python (qrcode, requests) - Frontend: Streamlit + Custom CSS - Hosting: Multi-service fallback system (Catbox, Pixeldrain, 0x0.st) 💡 Key Features: ✅ Generate QR codes from text/URLs instantly ✅ Upload ANY file type (PDF, images, videos, docs) ✅ Smart backend that tries 5 hosting services automatically ✅ PERMANENT links that never expire ✅ Custom color options ✅ Professional, responsive UI 🎯 The Challenge: Most file-sharing services expire links quickly. I built a cascading upload system that prioritizes permanent storage providers. 🏗️ Architecture Highlights: - Clean OOP design with modular QRCodeGenerator class - Sequential service fallback with error handling - RESTful upload API integration - Session state management in Streamlit 🔗 Live Demo: https://lnkd.in/gyCPnTPn 💻 GitHub Repo: https://lnkd.in/gZk8zkFZ #Python #WebDevelopment #FullStack #Streamlit #QRCode #BackendDevelopment #API #SoftwareEngineering #OpenSource #Tech #Programming
