I deliver global SAP HR and SuccessFactors transformations across multi-country enterprises.
FranceWhat I'm looking for
I've spent 15 years delivering, maintaining, and migrating SAP HR solutions across complex international environments. At L'Oréal, I supported global SAP HR and SuccessFactors Employee Central initiatives spanning more than 40 countries.
I've led functional specifications, data migration, UAT, go-live, ongoing support, and payroll centralisation for programmes including OneProfile and OnePayroll. I bridge HR and technical teams while driving knowledge transfer across geographies.
Earlier, at ALTI - TCS, I delivered SAP HR deployment, configuration, testing, reporting, and AMS for clients including L'Oréal, FMC Technologies, Air France, Generali, Sanofi, and Canal+.
I'm also the co-founder and product manager of WallOfTraders.com, a B2C crypto trading SaaS platform. Alongside product management and user support, I've explored Python, machine learning, deep learning, robotics, and crypto financial prediction.
