Rommel Bartolome
I'm a data guy — a data & analytics leader with 12+ years turning messy numbers into business impact, and 10+ years building high-performing analytical teams. Fintech, retail, sports integrity, clinical research: wherever I go, I create impact.
AI. Process. Transformation.
Three levers I pull in every role — whatever the industry. I believe in Kaizen: relentless, compounding improvement.
Put AI where it pays
I deploy AI where it moves a real number: AI-driven screening that cut error rates from 85% to 49%, AI-augmented forecasting that reduced prediction error by over 40%, and automation that has saved hundreds of work-hours a year — always lean, always measured by ROI.
Systems beat heroics
I build the boring things that make excellence automatic — ticketing systems, SLAs, sprint cadences, quality loops. The results follow: 97% error-free operations, 24x growth in analytics adoption, and teams that run reliably without a hero in the loop.
Change how the business works
I lead the shifts that stick: fraud overhauls that cut losses by 99% and lifted clean responses from 81% to 99%, cloud data platforms architected from the ground up, and analytics cultures that replace anecdotes with forecasts in the leadership room.
Wherever I go,
I create impact.
Led the risk team at a leading fintech that cut fraud and abuse losses by 99% through end-to-end partner risk controls.
Grew analytic tool usage 24x (and daily active users 13x) across 100+ companies of a major retail group.
Launched statistical models and AI-driven workflows that slashed forecasting error in clinical-trial recruitment.
Systematic process and tooling improvements that made reliable delivery the default, not the exception.
