You will get a fast Progressive Web App with offline support and push notifications
Project details
You will get a fully functional Progressive Web App (PWA) built with modern web technologies. Your website will work offline, be installable on any device, and send push notifications to keep your users engaged.
I specialize in converting existing websites and React apps into fast, reliable PWAs with a 90+ Lighthouse score. Using Service Workers, Web App Manifest, and smart caching strategies, I deliver apps that feel native on both mobile and desktop.
What makes my service stand out:
✓ Works offline — no internet required for core features
✓ Installable — users add it to their home screen like a native app
✓ Push notifications — re-engage your users automatically
✓ 90+ Lighthouse performance score guaranteed
✓ Clean, documented source code included (Advanced tier)
✓ Responsive design across all screen sizes and devices
Whether you have a React app, a plain website, or a business platform, I will make it work like a native app — without the App Store fees.
