Share a case when you offered the customer a more optimal solution.

In one of the projects, the client planned to use a monolithic application for processing large volumes of data, which could lead to scalability and performance issues.

I suggested switching to a microservices architecture using message queues for asynchronous data processing. This allowed to offload the system, increase fault tolerance, and simplify scaling of individual components.

As a result, the client received a more flexible and efficient solution that better met the growing business requirements.
