Mobile App Rebuild on Bubble.io

I'm seeking an experienced Bubble.io developer to rebuild an existing web-based app into Bubble's new mobile app engine for native deployment on iOS and Android. The UI is fully designed, and the feature set is mapped out. This project involves reimplementing existing features, optimized for mobile layout, navigation, and performance.

Key Requirements:
- Rebuild ~9 core feature pages into Bubble's mobile version
- Implement login, sign-up, password reset (basic auth flow)
- Create a responsive settings page with toggles and account options
- Set up navigation between features (bottom nav or custom states preferred)
- Optimize all pages for mobile speed and transitions
- Ensure clean logic structure for potential scale

Must be fluent in Bubble's new mobile version and experienced with:
- Responsive/mobile-first logic
- Native wrapping best practices
- Smooth UX transitions

Additionally, some third-party APIs like payment gateways and OpenAI need to be integrated.

Ideal Skills & Experience:
- Proficiency in Bubble.io, especially the mobile platform
- Experience with third-party API integrations
- Strong understanding of mobile UX/UI principles
- Background in app performance optimization

Will send the scope to interested candidates. Looking for a ballpark quote and timeframe.
