After two years of preparatory classes, I earned my degree from the Grande École Program with a specialisation in sustainable finance. Wanting to combine market finance and data, I chose the MSc Finance and Big Data, an English-taught program perfectly aligned with my ambition to pursue an international career and join major investment banks and asset management firms. This Master of Science blends technical skills (Python, C++, R)—essential tools in the market finance sector—with core disciplines such as quantitative analysis, portfolio management, and optimization. Taught by recognised experts in their fields, the MSc Finance and Big Data program will equip me with the skills needed to evolve as a portfolio manager while integrating a sustainable dimension. Finally, the school’s and program’s reputation, as well as the work-study format, will strengthen my profile by providing indispensable practical experience in the field.
