Why was the anti-fraud check service added to the candidate's responsibility zone?

Adding an anti-fraud check service to the candidate's area of responsibility is usually associated with the need to enhance the security and reliability of the system, as well as to ensure control and prevent fraudulent activities.

The reasons may include:

• The candidate possesses the necessary knowledge and experience in building high-load and secure services.
• The anti-fraud service is closely integrated with other components managed by the candidate, which simplifies communication and accelerates development.
• Centralized management of transaction or user action verification logic is required.
• The company aims to minimize financial loss risks and reputational risks, thus trusting this important part to a reliable specialist.

Therefore, expanding the responsibility area to include the anti-fraud check service is a strategic decision aimed at improving the quality and security of the product.
