Simulation Details

Fides is a global leader in banking software solutions, renowned for its high-performance systems that prioritize reliability, security, and scalability. Supporting financial institutions worldwide, Fides processes over 10 million transactions daily during peak periods, with downtime averaging less than 0.01% annually. The company’s architecture leverages cutting-edge technologies like Redis for high-speed in-memory caching and RabbitMQ for robust message brokering, integrated into a PHP-based transaction handling module built on the Laravel framework. Recent system upgrades aimed at enhancing real-time processing and compliance inadvertently introduced anomalies, disrupting banking operations and impacting millions of customers. Fides is committed to resolving these challenges swiftly to maintain its reputation as a dependable provider of scalable fintech solutions.

You will step into the role of a PHP Developer tasked with resolving a critical malfunction in Fides’ transaction handling module. Collaborating with Arjun Mehta, the Senior Technical Lead, you will analyze and edit a PHP code snippet to address issues in Redis caching and RabbitMQ message queues. Arjun will provide detailed feedback on problematic patterns, such as hardcoded TTL values and missing retry mechanisms, while leaving the responsibility of implementing fixes to you. Sofia Alvarez, the Engineering Manager, will set clear expectations and ensure you have the resources needed to succeed. Your mission is to deliver efficient, maintainable solutions that restore system reliability and scalability, aligning with industry best practices.

– Collaborate with Arjun Mehta to review the PHP code snippet and identify flaws in Redis caching and RabbitMQ logic.
– Edit the code to implement fixes, such as dynamic TTL values for Redis keys and robust retry mechanisms for RabbitMQ message handling.
– Ensure the solution adheres to industry standards and avoids introducing new vulnerabilities or regressions.
– Restore system functionality, reducing transaction failures and delays to pre-malfunction levels.
