Tell me about the most challenging task in your last project. Did you have to take on additional responsibilities?

In the last project, the most challenging task was implementing a high-load microservice for processing streaming data in real-time with minimal latency. It was necessary to ensure scalability and fault tolerance while processing millions of events simultaneously.

Additionally, I took on extra responsibilities for optimizing the architecture of interactions between services and implementing monitoring and alerting systems to quickly respond to failures and bottlenecks. This significantly improved the stability and performance of the system.
