Cross-Platform App Development Needed

I'm looking for a skilled developer to create a cross-platform app for Android, iOS, and Web. The app's primary function will be discussed further, but it must include robust user authentication using email/phone number and password. The app should also feature secure user profiles with two-factor authentication, data encryption, and profile privacy settings.

Key Requirements:
- Develop a cross-platform app for Android, iOS, and Web
- Implement secure user authentication and profile features
- Integrate AI/moderation filters for content moderation and spam detection
- Collaborate closely with the product lead to refine features

Ideal Skills and Experience:
- Proven expertise in developing scalable, high-availability applications
- Experience in cross-platform app development
- Strong knowledge of secure authentication methods
- Proficiency in implementing UI/UX designs
- Familiarity with AI technologies for content moderation and spam detection

I'm eager to work with someone who can bring this project to life while ensuring top-notch security and user experience.
