This isn’t a book about AI theory. It’s the exact stack I use every day.

No neural network diagrams. No Python notebooks. No prompt-engineering frameworks with made-up acronyms. This is the tools, the workflows, and the uncomfortable truths — from the first conversation with Claude to deploying a live application, from automating browser workflows to the geopolitics that decide which AI models you can actually trust.

It goes from zero to deep: every chapter assumes you know nothing, then goes further than most paid courses. And it’s honest — no sponsors, no affiliate links, no reason to be nice about any product.

Dennis Vorobyov is the CEO and co-founder of EltexSoft, a boutique software engineering studio he built from scratch in 2015 to a team of 35–50 engineers. EltexSoft has shipped 100+ projects for clients from early-stage startups to Fortune 500 enterprises, with teams in the United States, Portugal, and Ukraine. He moved his family to Lisbon and reorganized operations while Russia’s full-scale war on Ukraine was ongoing in 2022. By mid-2023 he had reworked about 90% of the company’s workflows around AI. 42: The AI Builder’s Stack is what he learned — a practitioner’s framework for how AI capabilities build on one another, from the first prompt to organization-wide transformation.
