Description

Senior Engineer in Generative Artificial Intelligence, I specialize in designing tailor-made AI solutions, from functional prototypes to production deployment (AWS, GCP). I am involved in the entire AI project lifecycle, with expertise in developing autonomous agents, RAG (Retrieval-Augmented Generation) systems, vector databases, and integrating LLMs like GPT-4, Gemini, Llama, Claude, or Mistral.

I have successfully developed and deployed several LLM-based applications. My solutions are based on frameworks like Langchain, LangGraph, or LlamaIndex, and I am also proficient in fine-tuning tools (QLoRA, PEFT) and monitoring tools (LangSmith).

My approach is pragmatic: understand business needs, prototype quickly, industrialize cleanly, and ensure scalable performance. I am also comfortable with real-time voice integrations (OpenAI Realtime API), and I have strong experience in mobile development (iOS), which allows me to deliver fluid user experiences on various platforms.

Having had international experience in the United States for 5 years, I am bilingual in English/French and fully operational for remote missions with French-speaking or international teams.
