About Lilian

Passionate about artificial intelligence and Data Science, I support my clients from start to finish in the design, scoping, and deployment of robust and truly usable AI solutions in production.

My added value lies in my ability to deeply understand business needs, translate them into relevant AI architectures, and then implement performant and maintainable solutions. I provide both consulting (technological choices, feasibility, architecture, ROI) and operational implementation.

I master AI applied to production, notably:

Machine Learning & Deep Learning

Generative AI (LLM, RAG, agentic systems)

Orchestration with LangChain / LangGraph

Data pipelines and integration into existing environments

With my experience in R&D at NVIDIA and Capgemini Engineering, as well as startup missions, I have worked on high-tech value projects: realistic virtual simulations, intelligent decision support systems, complex signal analysis, and integration of AI models in demanding industrial contexts.

I place particular importance on the reliability, performance, and adoption of solutions, with a pragmatic, impact-oriented approach. I enjoy intervening where it is necessary to conceptualize the solution, make the right technical choices, and execute.

👉 Looking for a profile capable of bridging the gap between business, advanced AI, and operational deployment?
I am available to advise, design, and implement your AI and Data Science projects.
