About Zacharie

Senior Data Scientist avec une these en Intelligence Artificielle et une expérience terrain dans des environnements R&D de pointe (supervision par des directeurs de recherche chez NVIDIA et Google), je conçois des solutions ML qui passent du prototype à la production, pas juste des notebooks qui prennent la poussière.
Ce que j'apporte à vos projets :
Mon parcours combine recherche académique et déploiement industriel. J'ai notamment mené un projet de reinforcement learning de la phase exploratoire jusqu'à son adoption à l'échelle d'une entreprise entière. Cette double casquette me permet de construire des solutions à la fois rigoureuses sur le plan scientifique et robustes en production.
Mes domaines d'expertise :

Prévision de la demande et séries temporelles
Reinforcement learning appliqué à l'optimisation logistique et pricing
Computer vision et NLP
Intégration avec systèmes ERP/CRM (SAP, Salesforce)

Types de missions que je prends en charge :

Audit et cadrage de vos besoins en IA/ML
Développement de modèles prédictifs end-to-end
Optimisation de processus métier par l'IA (stocks, prix, routing)
Mise en production et industrialisation de POCs existants
Conseil stratégique sur votre roadmap data/IA

Pour qui ? Retailers, e-commerce, supply chain, ou toute entreprise qui veut extraire de la valeur concrète de ses données sans se noyer dans la complexité technique.
