What additional features or extensions have you implemented in standard continuous integration and delivery systems?

Additional capabilities that can be integrated into a standard CI/CD system include:

• Automated testing and static code analysis — integration of linters, testing frameworks to improve quality.
• Parallel task execution — speeding up builds through parallelization.
• Notifications and reports — sending build and test results to messengers or email.
• Dynamic scaling of build agents — automatically adding resources under load.
• Integration with artifact management systems — storing and versioning builds.
• Security — vulnerability scanning, secret management.

For example, you can add a stage of automatic deployment to a test server after successful tests, which will speed up the development cycle and increase reliability.
