About Nicolas

Entrepreneur, with over 10 years of experience in digital and consulting, I have supported major brands on data and digital marketing topics.

After founding and managing Clustaar SEO & Data from 2013 to 2020, I decided in mid-2020 to dedicate myself entirely to data marketing topics and the new opportunities offered by the cloud.

Today, I help marketing teams take control of their data to measure and improve the ROI of their digital investments.

Areas of expertise:
- Web analytics and advertising tracking (web and mobile app)
- Consent management
- Data engineering (creation of ETLs and Data warehouses)
- Activation (Dashboarding, reverse ETL...)

Common technologies:
- Tracking: Google Tag Manager, Google Analytics, GA4, Firebase, Matomo, AT Internet, Segment + Consent management platforms (Didomi, CookieBot, OneTrust)
- Data pipelines and connectors: Fivetran, Funnel, Supermetrics..
- Cloud data warehouse: Google Big Query
- Visualization and exploration: Google Data Studio, Dataiku, Metabase

Nicolas demonstrated strong expertise in data and marketing subjects more broadly. He assisted us in the context of an architecture audit which he brilliantly conducted by applying a solid end-to-end methodology.
