About me
Intro
With a double background in engineering and management, I’ve built my career at the crossroads of technology, data, and business performance. After four years at Dassault Systèmes supporting digital transformation for CAC40 customers, I joined EPISOD as the COO’s right-hand, overseeing millions in budgets, managing strategic partnerships, and driving €100K+ new monthly recurring revenue through data-driven operations. I thrive in fast-paced, tech-driven environments where I can bridge strategy.
