AI/ML engineer who deployed RAG pipelines and CrewAI agents at ITG Consultants and production NLP models at Interflora.

France

Message

At ITG Consultants, I designed and put RAG pipelines for complex technical documents and CrewAI agents into production. I also served open-source models with vLLM and integrated managed Claude, GPT, and Mistral endpoints.

At Interflora, I trained and deployed a multi-label NLP classifier with Hugging Face and SetFit, achieving F1 above 0.85 per class. I also built geospatial supply-chain models that generated €500,000 in annual savings, and deployed sales-forecasting pipelines.

Earlier, I modeled LTV, churn, and ranking for B2B SaaS clients as a consultant at ITG Consultants. At GL events, I managed market intelligence work, including an indexing and monitoring engine handling more than 10 million pages per year.
