Adam Rojek is co-founder and CTO at Fluid, where he led the technical direction of the cashier platform from its earliest architecture decisions through to a production system trusted by licensed iGaming operators.
With over 20 years in software engineering, Adam's career spans extended stints at money-moving platforms in regulated industries. At Fluid he set the technical bar for how the product is designed, built, and operated — defining the service architecture, the payment-integration patterns, and the engineering principles that allow Fluid to drop in front of an operator's existing PSP stack without becoming a liability.
Beyond architecture, Adam built the engineering team and the culture around it: hiring, mentoring, and shaping the standards by which the codebase is reviewed and shipped. He partnered closely with the rest of the founding team on company strategy, and was a recurring presence in technical conversations with clients and partners — translating between operator requirements, PSP realities, and what the platform could responsibly commit to.
Adam's engineering philosophy is conservative in the right places: payment code paths must be observable, idempotent, and recoverable, because the alternative is a player whose money is in limbo and an operator whose finance team spends Monday reconciling it. The opinionated parts of Fluid — the component model, the AI tuning loop, the per-operator personalisation layer — reflect the trade-offs he chose to make explicit rather than defer.
He writes about technical leadership in payments, software architecture for regulated systems, integration patterns for iGaming PSPs, and the operational realities of running a cashier in production.
