John Flynn is a senior casino reviewer and iGaming writer based in Dublin, Ireland. He has spent more than eight years testing online casinos, evaluating bonuses, and breaking down payment methods for Irish players. His work at GreenInfrastructure.net focuses on helping everyday players make informed decisions — without the marketing spin.
Before moving into gambling content, John worked in consumer finance journalism, which gives him a sharp eye for bonus terms, wagering conditions, and anything that looks good on the surface but hides a catch underneath. He takes pride in reviewing casinos the way a real player would — by depositing real money, testing withdrawals, and reading the fine print.
About John Flynn
John grew up in Dublin and studied journalism at Dublin City University. After graduating, he spent several years writing about personal finance and consumer rights before discovering that the online gambling space was badly in need of honest, reader-first content. He joined GreenInfrastructure.net in 2018 and has been the lead reviewer ever since.
He has personally tested over 120 online casinos available to Irish players, with a particular focus on licensing, payout speed, and bonus fairness. John is a strong believer that a casino’s withdrawal process tells you more about it than any welcome bonus ever will.
When he is not reviewing casinos, John follows Gaelic football, is an occasional poker player, and keeps a close eye on developments from the Gambling Regulatory Authority of Ireland (GRAI).
