About Adrien

Tracking and Data Analytics Specialist, I ensure the implementation, monitoring, and reliability of data collection on Web environments, respecting RGPD legislation and user consent. My technical approach focuses on Data Quality, report monitoring, identification of tracking anomaly causes, and correction of data discrepancies.

My expertise also draws on a strong marketing and advertising dimension. Having managed the acquisition for over a hundred e-commerce accounts (Meta/Facebook Ads) and conducted large-scale advertising quality audits, I understand the direct impact of faulty tracking on return on investment. The objective is to structure a robust analytical environment for precise strategic and budgetary management.
