What I'm looking for

I'm open to remote work within Europe.

At Tornado Games, I own the maths models, mechanics, and payout structures for online slot and casino games. I build C++, Python, and Excel simulations to tune RTP and volatility, then verify production builds against the certified maths model.

At Expenti, I delivered game maths for titles in regulated and unregulated markets and validated each title with my own C++ simulator. My work included Crystals on Fire, Realm of the Gods, and River of Gold.

At Zitro, I designed and validated land-based slot maths for the Mexican, Spanish, and US markets, including Fu Frog and Wheel of Legends. I also led the maths team for a period, planning tasks and delivery timelines while staying hands-on with modelling and simulation.
