Android Developer Needed for IPTV App Upgrade

I'm looking for an expert Android developer to update and enhance my IPTV Code Generator App. The project includes:

- **User Interface Improvements**: The current UI needs a refresh to make it more user-friendly and visually appealing.
- **Code Generation Speed Optimization**: The speed of code generation needs to be improved for a better user experience.
- **New Feature Additions**: I would like to incorporate several new features, including:
- Advanced code customization options
- Code expiration reminder notifications
- Multi-language support

The app should be compatible with:
- Mobile Phones
- Tablets

Ideal candidates should have extensive experience in Android app development, particularly with UI/UX design and performance optimization. Experience implementing multi-language support and notification systems is a plus.
