About Marc
Data Engineer Consultant with over 10 years of experience,
graduated with a Master’s degree, in Software Engineering in 2016. I quickly specialized in data, with strong expertise in ETL and Big Data.
I have worked at Atos and Keyrus, where I collaborated with major clients such as LVMH, BNP Paribas, and Thales.
I am currently on a permanent contract (CDI) with Thales Services Numériques (TSN), where I have been working for the past 3 years on a mission for one of its major clients.
Certified in Hadoop HDP (2017), Spark (2018), and recently Google Cloud Professional Data Engineer (2025), and Google Professional Machine Learning Engineer (2026)
- Data quality is my credo: I implement automated testing and never deliver code without tests
- My work is always delivered with proper documentation (installation and operations)
- Experienced in handling large-scale data volumes, I focus not only on delivering solutions but also on optimizing them for better processing and query performance while minimizing costs
Highly passionate about my field, I am currently seeking evening and weekend projects where I can apply my expertise to ambitious initiatives, particularly around Hadoop, Big Data, and Cloud technologies.
