Improve React Native page (layout, speed, etc.) for FB-like post-detail (Expo)

Need React Native guru to help improve Post Detail + comments page. The page needs to look and work very, very similar to Facebook post detail + comments page. Note: a lot of code is already written (see attached). This project should take 2-3 hours for experienced RN developer. Requirements: - Use FlatList, every comment or subcomment should be rendered as an element in this list (currently subcomments are rendered inside parent comment element. - Should perform well (fast) with up to ~500 comments. - When replying to one comment or subcomment, all others should be disabled (currently it works for comments but not subcomments) - Sticky footer needs to avoid (move up with) keyboard - Comment input should grow to multiple lines (see PDF attachment). - Add "like count" bubbles to each comment (like Facebook) - Improve haptic feedback on "Like" (shorter vibration on iPhone. Use Expo Haptics/Taptic IOS?) - Improve styling (flexbox, avoid negative margins if possible)
