About Zacharie

Senior Data Scientist with a PhD in Artificial Intelligence and hands-on experience in cutting-edge R&D environments (supervised by research directors at NVIDIA and Google). I design ML solutions that move from prototype to production, not just dusty notebooks.
What I bring to your projects:
My background combines academic research and industrial deployment. I led a reinforcement learning project from its exploratory phase to its adoption across an entire company. This dual expertise allows me to build solutions that are both scientifically rigorous and production-robust.
My areas of expertise:

Demand forecasting and time series
Reinforcement learning applied to logistics optimization and pricing
Computer vision and NLP
Integration with ERP/CRM systems (SAP, Salesforce)
Types of projects I undertake:

Audit and scoping of your AI/ML needs
End-to-end predictive model development
Optimization of business processes using AI (inventory, pricing, routing)
Production deployment and industrialization of existing POCs
Strategic consulting on your data/AI roadmap
For whom? Retailers, e-commerce, supply chain, or any company that wants to extract concrete value from its data without getting bogged down in technical complexity.
