What build and deployment automation systems have you used in your projects?

In projects, I have used various build and deployment automation systems, including:

• Jenkins — for creating CI/CD pipelines with flexible task configuration.
• GitLab CI/CD — an integrated solution for automating processes within GitLab.
• Travis CI — for automatic building and testing of projects.
• Docker and Docker Compose — for containerizing applications and simplifying deployment.
• Ansible — for automating server configuration and deployment.

The choice depends on the project requirements, infrastructure, and team preferences.
