À propos de Maximilien

I build AI Agents and RAG architectures for industry leaders, with a specialization in Healthcare.

With a background at Roche and NVIDIA, I bridge the gap between cutting-edge research and scalable industrial applications. I help companies transform proprietary scientific data into actionable intelligence through autonomous AI agents.

Track Record:

  • Roche: Architecting LLM solutions to accelerate the molecular life cycle.
  • NVIDIA: Optimizing 3D medical pipelines for real-time surgical use.
  • Jengo: Built multi-channel AI Agents as CTO/Lead Engineer.
  • MICCAI: 3rd place worldwide at the 2023 3D tumor segmentation challenge.

Why work with me?

  • Domain-Specific RAG: Architecting high-precision retrieval pipelines optimized for restricted, proprietary, and scientific datasets.
  • Healthcare & BioTech Focus: Proven expertise in handling clinical data, 3D medical imaging, and navigating strict regulatory compliance.
  • Production-Grade Infrastructure: Deploying scalable, real-time AI solutions directly to production using AWS or GCP

Nous avions deja collaboré avec plusieurs freelances en IA, mais Maximilien s'est vraiment démarqué. Il a dépassé nos attentes dans la réalisation de 2 projets de R&D que nous lui avions confiés. Maximilien est toujours à l'affut des dernières avancées en IA lui donnant une capacité à générer des effets de levier considérables, là où beaucoup d'ingénieurs cherchent seulement à améliorer l'existant de 10%. Un profil rare, que nous recommandons vivement.
