Comprehensive PowerShell automation system that works across Windows, Linux, and macOS. Covers everything from basic scripting to CI/CD pipelines in GitHub Actions and Azure DevOps, plus cloud automation with Az, Microsoft.Graph, and AWS modules. The strength here is the reference system: it splits cross-platform patterns, module management, pipeline configs, syntax, and security into separate docs so you only load what you need. Ships with practical guardrails like the pre-flight checklist and a production-ready script skeleton. Opinionated about PowerShell 7+ over legacy 5.1, backslashes on Windows, and keeping your repo clean. If you're doing any serious shell automation or cloud orchestration, this gives you the patterns without the guesswork.
