CI/CD with GitHub Actions

The article explains how GitHub Actions powers CI/CD automation directly from a GitHub repository.

It walks through core concepts like workflows, jobs, steps, runners, and reusable actions.

Sample Node.js and Python workflows show testing, linting, caching, matrix builds, and coverage reporting.

It also includes security checks such as Bandit and pip-audit to catch vulnerabilities early.

The main takeaway: teams can reduce manual release work and improve code quality with automated pipelines.
