Gustavo Lima builds and operates the systems this series describes. His work spans Europe's largest lottery group and the construction of more than 50 online casinos across 12+ jurisdictions, from Curacao and Malta to Brazil and the United States, including sportsbook infrastructure scaled for Super Bowl traffic, when betting volume multiplies within minutes and capacity planning gets no second chance.

That experience covers every seat at the table: choosing jurisdictions and carrying licence applications, contracting platforms and game suppliers, standing up payment operations, building and leading engineering and operations teams, and answering to regulators and auditors once the platforms are live.

He is the author of The Backend of Luck: Engineering the Online Gambling Platform, a six-volume technical series, and of the standalone guide How to Open an Online Casino. He publishes through Brainiacs B.V. in The Hague, the Netherlands.
