About Jerome

Your AI in production, without breaking the bank.

Senior AI Engineer (CNAM, ex-Thales), I help companies integrate Artificial Intelligence into their core business processes. Moving beyond trivial "POCs," I design robust, secure, and above all, profitable applications.

My approach is strongly focused on "FinOps LLM": I ensure your API calls (OpenAI, Anthropic, Google) are optimized to the nearest euro to safeguard your budget.

🛠️ What I can build for you:

RAG Systems (Retrieval-Augmented Generation): Discuss with your own private data (tenders, technical documentation, legal documents) without hallucination.
• **Automation & AI Agents**: Replacement of repetitive tasks with intelligent pipelines.
• **AI Audit & FinOps**: Analysis of your existing applications to halve or triple your API costs through proper model routing.

💻 My technical stack:

• AI: OpenAI, Claude, Gemini, LangChain, Embeddings
• Backend: Python, FastAPI, PostgreSQL, SQLite
• Architecture: Docker, Traefik, secure environments

Methodical and oriented towards "iterative delivery," we move forward in short sprints so you get ROI quickly. Let's discuss your use case!
