Tell me about the most challenging problem you faced in your last project.

In the last project, one of the most challenging problems was configuring the CI/CD pipeline for automatic deployment of microservices in Kubernetes. The main difficulty was in correctly configuring Helm charts and managing secrets, as well as ensuring seamless updates of services without downtime. To solve this, it was necessary to thoroughly study the documentation, set up canary releases, and integrate monitoring to quickly identify and roll back problematic updates.
