About Marc-Henry

Welcome to my profile!


With a background in computer science and a specialization in AI, I have spent over 6 years building robust data architectures and leveraging complex data.

My experience has allowed me to work across the entire value chain: from researching predictive models in innovation labs to managing large-scale platforms, notably at Orange and Amadeus. My experience as a Tech Lead and Product Owner allows me to support my clients with a dual perspective, both technical and product-oriented.

Feel free to contact me if you are looking for expertise such as:
  • **Data Engineering**: Creation of ETL pipelines (Python, Scala, Spark) and database management.
  • **Cloud & Streaming**: Real-time streams with Kafka and cloud migration.
  • **Data Science & Analytics**: Data visualization, financial dashboards, and predictive modeling

Whether working independently or as part of a team, I am committed to the technical quality and performance of my deliverables to concretely meet your business needs!
