Facebook Game with Customizable Avatar Faces

I'm in need of an innovative app for a Facebook Instant game that encompasses unique avatar customization features. The main highlight should be facial alterations on avatars used within the game. Even though my preference on detailed facial customization options wasn't stated, potential applicants must have experience with universally accepted elements like skin tone, eye shape and color, and hair style and color. Expertise in creating engaging avatar-based apps is the key to being successful for this job. This game will not include multiplayer games or leaderboards at this time, however the ability to scale and add additional features is important.

I'm seeking a skilled app developer to create a highly interactive app, centered on an engaging avatar facilitating patient interaction. The proposed app is to connect healthcare providers and patients, facilitating dialogue through an AI-driven question-answer model, developed using ChatGPT.

Functionality:
- User-focused interaction with an avatar
- AI-fueled question series from the avatar
- Personalized responses from the avatar based on user inputs
- Collation of user responses into a prefilled document

Key features of the avatar include:
- Capability to post questions
- Deliver tailored responses

The app should be accessible on multiple platforms, namely iOS and Android.

Ideal Skills:
- Proficiency in AI-based app development
- An understanding of healthcare dialogue context
- Prior experience in creating interactive avatar apps
- Knowledge of cross-platform app development

Your previous experience in similar projects and your ability to deliver a user-friendly interface will be valuable for this project.
