O Engenheiro Livre

“The Free Engineer”

AI, Code and Reclaiming Professional Autonomy

by Carlos Eduardo Gonçalves Keese

Written in Portuguese.

A book about the comfortable cage designers have been placed in — and about how to get out of it without giving up the tools that work. It starts from a concrete observation: the price of computing power is no longer measured in money per licence but in structural dependence. The more power artificial intelligence delivers, the deeper the professional sinks into the silo that delivers it.

  • A six-lock test — data, tools, capability, intelligence, income and domain — to measure, in ten minutes, how much of your craft depends on others. You take it again at the end of the book.
  • The history of the enclosure: from the drawing board to CAD, from CAD to proprietary formats, from formats to cloud subscriptions, and from the cloud to the copilot that only works inside it.
  • The programmer-designer as a hybrid species, and CAD splitting between open protocols and digital fiefdoms.
  • AI as a tool, not an owner — including what it costs when the relationship flips.
  • A practical appendix, from the first line of code to the first automation that saves your day.

Handbooks and technical material

Reference and course material: shorter and more direct, made to stay open next to your work.

Nothing published in this section yet. When material is ready it will appear here — only what exists as a file gets in, not intentions.

Why the download doesn't ask for your e-mail

The industry norm is to trade a PDF for an e-mail address, and then use that address. Not here: the button is a direct link to the file. If the text is worth anything, you'll come back of your own accord — not because a mailing list reached you.

Where the file lives. Right here. The rest of the site distributes through GitHub Releases, because there the file is a by-product of versioned code — a book has no tag or build, so that route doesn't fit. The next attempt was a cloud-storage link, and it landed on a login screen that had nothing to do with you. Serving the PDF from this domain solved both: the download is direct, and it doesn't depend on a link that can be revoked without anyone noticing.
