About Clément

I have been supporting companies for 10 years in the implementation, optimization, and exploitation of their digital measurement systems, in order to ensure the reliability of their data and maximize their marketing performance.

💡 Here's how I can help you:
  • Build or redesign clear web and app tagging plans that comply with best practices (Analytics, attribution, media)
  • Design reliable datalayers and clean, sustainable GTM implementations (client-side or server-side)
  • Ensure compliance with GDPR and consent best practices for all tracking systems
  • Design multi-source dashboards (Analytics, media platforms, CRM...) aligned with the needs of marketing and management teams
  • Implement advanced media activation systems to improve campaign measurement and optimization: offline data import, CAPI, Enhanced Conversions...
  • Analyze conversion paths and funnels to identify concrete and actionable insights

🚀 My added value after 10 years of experience in media agencies

  • Strategic & operational vision: I connect business, media, and technical needs
  • Multi-platform expertise: GA4, Matomo, GTM, BigQuery, Looker Studio, CAPI, Google Ads, Meta, DV360, CM360, Adjust, Appsflyer, Firebase...
  • Pedagogy and knowledge transfer: I know how to simplify technical topics, support and train teams to become autonomous
Feel free to contact me to tell me more about your needs.
