About Antoine

Data Analyst Power BI | Expert Excel · SQL · Python

Avec 6 ans d'expérience en entreprise, dans l'industrie de l'eau (SIAAP) puis dans le retail (Groupe Invivo Teract), j'ai appris à travailler avec des données imparfaites, des délais serrés et des interlocuteurs qui n'ont pas le temps de déchiffrer des tableaux complexes.

Mon cœur de métier : concevoir des dashboards Power BI clairs, performants et réellement utilisés.
De la modélisation des données jusqu'au rendu visuel final, je prends en charge l'intégralité du processus : modèle de données, DAX, Power Query, storytelling et automatisation des rapports.

Excel, SQL et Python viennent compléter cette expertise.
Je m'appuie sur ces outils pour structurer, nettoyer et transformer les données avant de les valoriser dans Power BI, en m'adaptant à l'environnement technique de chaque client.
Je me forme actuellement sur Snowflake pour renforcer mon expertise sur les architectures cloud modernes.

Je m'approprie rapidement un nouveau contexte et j'identifie les problématiques avant même qu'elles soient pleinement formulées.
Curieux de nature, chaque sujet est une occasion d'apprendre et d'aller plus loin.
Rigoureux sur le fond, accessible sur la forme, et toujours orienté résultats.

    I assisted Léa in the statistical processing and analysis of her medical thesis data, focusing on the use of ultrasound in general medicine. My work involved cleaning and structuring the database, producing descriptive and bivariate analyses, and performing appropriate statistical tests to identify factors associated with ultrasound equipment and usage.

I called on Antoine for my general medicine thesis. The work was thorough and met my expectations. The analyses are clear and the explanations are accessible, which is appreciated when one does not have extensive training in statistics. The exchanges were fluid and the deadlines were met. I recommend him for reliable support in statistical analysis.

I recommend Antoine, we worked together on the statistics for my medical thesis. He performed the analysis of all the data from a Google Form. He used Python and Excel software for the visualizations. I sincerely thank him for his tailor-made support.
