Jonathan in a few words

Diplômé d'ESCP Europe, je travaille depuis +6 ans dans le secteur de la data.
Fort d'expériences acquises au sein de différents types de structures (agence, annonceur, prestataire technologique) et de différentes tailles (startups & grands groupes) dans le secteur digital, je souhaite aujourd'hui mettre à disposition mon expertise aux marques afin de les aider à mieux capitaliser sur leurs données et optimiser leur marketing digital. J'exerce auprès de tout types de structures (startups, grands comptes, PME, agences...).

Au cours de mes expériences, j'ai été amené à développer une expertise sur un grand nombre de problématiques et d'outils liés à l'usage de la donnée :
- Web & UX Analytics : Google Analytics, AT Internet, Content Square
- Product Analytics : Amplitude, Mixpanel
- Data Visualization : Tableau, Data Studio, Metabase, Looker
- Data Collection : Google Tag Manager, Segment, Adobe
- Data Processing : Google BigQuery, Amazon Redshift, Snowflake
- Data Activation : SEA, Facebook Ads, RTB, Display, Retargeting
- Web & Mobile attribution : Eulerian, Mazeberry, Adjust, Appsflyer, Tune, Kochava
- Data Analysis : SQL, Python

J'apprécie notamment travailler en collaboration avec les équipes marketing et produit afin de les accompagner sur des problématiques d'acquisition, de rétention, d'engagement et de conversion.
