Do you have experience working with systems that are in production stage?

Yes, experience working with systems in production includes support, monitoring, and optimization of running applications. In production, it is important to ensure stability, respond quickly to errors, and use resources efficiently.

For example, when working with a web service in Python, you can use logging, performance monitoring (via Prometheus, Grafana), as well as automatic scaling and data backup. It is also important to be able to quickly deploy updates and roll them back if necessary.
