React Native Pre-Launch Code Audit

I'm seeking a comprehensive pre-launch code audit for my React Native application. The focus areas are FlatList performance, Firestore query optimization, and Security Rules validation. All three are equally critical.

Key Requirements:
- React Native FlatList Performance: Analyze and optimize rendering of dynamic data to ensure smooth scrolling and reduced latency.
- Firestore Query Optimization: Review and enhance composite queries with multiple conditions, ensuring efficient data retrieval and minimizing read operations.
- Security Rules Validation: Audit current security rules for Firestore to ensure data protection and integrity.

Ideal Skills and Experience:
- Expertise in React Native, specifically with FlatList and performance optimization.
- Strong knowledge of Firestore, especially with composite queries.
- Experience in validating and implementing security rules for Firestore.
- Prior experience with pre-launch audits is a plus.

Please provide a detailed plan on how you will approach this task, and any relevant experience in your bid. Thank you!
