Anti-Fraud Detection App Development

I need an anti-financial fraud app that primarily detects suspicious transactions. The app should use a combination of machine learning algorithms, rule-based detection, and user-reported flags. It must integrate with banking systems, e-commerce sites, and cryptocurrency exchanges.

Key Requirements:
- Detect suspicious transactions
- Use ML algorithms, rule-based detection, and user reports
- Integrate with multiple financial platforms

Ideal Skills and Experience:
- Expertise in machine learning and fraud detection
- Experience with app development and financial integrations
