A UCD computer science graduate with a data science focus, he blends backend systems work with practical dashboarding and observability using tools like Power BI. Outside of work he’s an avid cyclist and motorsport enthusiast, traits that mirror his preference for iterative performance gains and hands-on problem solving.
