About Marc-Henry

Bienvenue sur mon profil !



Fort de ma formation en informatique et de ma spécialisation en IA, je m’investis depuis plus de 6 ans dans la construction d'architectures data robustes et l'exploitation de données complexes.


Mon parcours m'a permis d'intervenir sur l'ensemble de la chaîne de valeur : de la recherche de modèles prédictifs en Lab d'innovation à la gestion de plateformes à grande échelle, notamment chez Orange et Amadeus. Mon expérience de Tech Lead et de Product Owner me permet aujourd'hui d'accompagner mes clients avec une double vision, à la fois technique et produit.


N'hésitez pas à me contacter si vous recherchez des expertises telles que:
  • Data Engineering: Création de pipelines ETL (Python, Scala, Spark) et gestion de bases de données.
  • Cloud & Streaming: Flux temps réel avec Kafka et migration vers le cloud.
  • Data Science & Analytics: Data visualisation, dashboards financiers et modélisation prédictive


Que ce soit en autonomie ou en renfort d'équipe, je m'engage sur la qualité technique et la performance de mes livrables pour répondre concrètement à vos enjeux business !
