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.
