I've led product, customer, and business analytics across Big Stars, GastFreund, Clarivate, Colgate-Palmolive, Nielsen, and Coca-Cola HBC Serbia. At Big Stars, I analyze feature adoption and downstream behavior in gaming products using cohorts, segmentation, experimentation, and predictive modelling.

At GastFreund, I defined product measurement, event taxonomy, tracking processes, and database structure during a migration from Google Analytics to Matomo. I also built a customer health prediction model and Customer Health Score to help Customer Success identify accounts at risk of churn.

I've established product-usage analytics for 18 BioPharma applications, designed KPI frameworks for more than 100 employees, and translated ambiguous stakeholder questions into analytical approaches, insights, and recommendations.
