Senior AI Engineer / Data Scientist specialized in Generative AI, Machine Learning and Production Deployment.
Returning from Australia after a professional experience in Sydney, I now wish to support companies that want to integrate AI in a serious, pragmatic, and sustainable way.
With several years of experience in machine learning, I naturally turned to Generative AI in early 2023 and had the opportunity to deliver several projects in production.
My expertise:
- Generative AI : RAG, AI agents, LangChain / LangGraph
- Machine Learning & Deep Learning : NLP, computer vision, scikit-learn, PyTorch, Hugging Face, MLflow.
- Backend & APIs : Python, FastAPI.
- Cloud & Production Deployment : AWS, GCP, Azure, Docker, Terraform, CI/CD
Types of missions sought:
- Identify and frame Generative AI use cases that are truly useful for your company.
- Develop an AI prototype and then industrialize it properly.
- Build an internal assistant, an RAG engine, an AI agent, or a business automation tool.
- Integrate LLMs into an existing application.
- Improve the quality, robustness, cost, or maintainability of an already launched AI project.
- Support a technical or product team in upskilling in applied AI.
I am bilingual in English/French, with an IELTS score of 8.5/9, and can also work in international environments.
