About

I write about infrastructure engineering, platform automation, tutorials, and business decision support.

About the Author

I am Ronaldo Dantas, Senior Data Center Expert and Enterprise Architect in São Paulo, Brazil, with 32 years in IT—25 at a single organization, spanning multiple names and technology changes.

I’ve built my career within complex, multi-tenant enterprise infrastructure environments far beyond typical demo scenarios. That depth shapes my perspective.

Recently, I’ve expanded into Platform Engineering—Terraform, Kubernetes, Cloud, Network automation, Python, Golang (Go), but because today’s most interesting challenges are at the intersection of infrastructure and automation.

Operating Systems & Infrastructure I’ve been working with Unix systems since 1996 — before Linux was a serious enterprise contender. Today, that foundation extends across Linux distributions in production environments, container runtimes, and the low-level OS behavior that most cloud engineers only encounter when something breaks at 2 AM. Thirty years of that muscle memory doesn’t go away; it just becomes pattern recognition.

Leadership & Communication With over thirty years in enterprise IT, I have seen that technical expertise alone is not enough. I have mentored engineers and led cross-functional infrastructure teams. My primary focus, and the purpose of this blog, is to translate complex infrastructure concepts into actionable language for non-specialists and IT . Architecture decisions are effective only when those implementing them understand their purpose.

Currently building

  • Infra-Mirror.com — (coming soon) A Go CLI that scans AWS infrastructure and generates Terraform HCL
  • ShowInt.ai — An AIOps tool for network fault analysis using LLMs
  • Terraform for Cisco ACI — A technical book for senior network engineers transitioning to IaC

Contact Me

The best way to reach me is by email. I’m also reasonably responsive on GitHub and LinkedIn if you’ve found a bug or want to contribute to one of the projects.
