What infrastructure setup and maintenance tasks have you performed yourself?

In my practice, I have independently performed the following tasks related to the setup and maintenance of infrastructure tools:

• Installation and configuration of application servers (e.g., Tomcat, WildFly).
• Setting up monitoring systems (Prometheus, Grafana) to track service status.
• Automation of deployment using scripts and CI/CD tools (Jenkins, GitLab CI).
• Database management: setting up backups, performance optimization.
• Configuring logging and log aggregation systems (ELK stack).
• Ensuring security: setting up SSL, managing access rights.

These tasks helped maintain the stable operation of applications and infrastructure as a whole.
