Math Analyst at Gaming Labs International, validating game models and simulations for payout structures and performance.

South Africa
Message

At Gaming Labs International, I develop and refine mathematical and probability models to evaluate game performance, payout structures, return to player, and volatility. I also run simulations and validate results against theoretical expectations.

I work with game designers and software developers to translate mathematical specifications into game functionality. I prepare specifications, par sheets, simulation reports, and technical documentation for model validation and regulatory certification.

At FNB (First National bank), I built predictive models to identify customers at risk of default and developed forecasting models for revenue planning and demand forecasting. I also created and maintained Power BI dashboards and SSRS reports to track business performance.

I automated reporting workflows, reducing manual reporting effort by 45%, and improved data quality by 30–40% through validation and data cleaning. My work spans predictive analytics, data platforms, and mathematical game simulations using Python, SQL, C++, and cloud services.
