Can you tell about your key tasks and responsibilities implemented at your previous workplace?

At my previous job, my key tasks and responsibilities included:

• Setting up and maintaining CI/CD pipelines for automating the build, testing, and deployment of applications.
• Monitoring and logging infrastructure using tools like Prometheus and Grafana.
• Managing configurations and automating deployment with Ansible, Terraform, or Kubernetes.
• Ensuring system security and backups.
• Collaborating with development teams to optimize delivery and support processes.

For example, I implemented automatic deployment of microservices in Kubernetes using Helm charts and integrated with Jenkins.
