a Data, Software Engineering and Product Leader.
Julien
I have held diverse leadership roles across the tech industry, including Head of Data Engineering, Head of Analytics, Senior Enterprise Architect, Product Manager, Scrum Master, Global Software Engineering Lead, and Global Data Science Lead. My experience spans the entire data and engineering value chain, allowing me to build and manage high-performing teams of engineers, analysts and data scientists, while also developing data strategies for large organizations.
I have successfully led the product definition, design, and development of customer data platforms, as well as guided engineering teams in setting up data platforms, data warehouses, and data marts as well as diverse applications. Additionally, I’ve spearheaded the integration of multiple financial systems, ensuring seamless operations and data consistency.
My journey began as one of the first Data Scientists hired at Amazon and Facebook in Europe, giving me a unique perspective on the evolution of data science. With hands-on experience as an Analyst, Data Scientist, Solution Architect, Enterprise Architect, and Engineer, I bring a comprehensive and strategic approach to every project I undertake.

My Tech Stack
I have extensive experience across various technologies, including cloud platforms such as AWS, GCP, and Azure, along with tools like Databricks and Airflow for data engineering. My DevOps skills encompass Docker, Kubernetes, Gitlab CI, and Terraform for efficient deployment and infrastructure management. I’m proficient in analytics tools like Tableau and Looker, and I’ve implemented machine learning models using Spark MLlib and XGBoost. While I primarily code in Python today, I also have a background in C, Java, and Scala, with experience in backend and frontend development using React and HTML.
