About Léo

I design and develop custom AI systems for businesses and freelancers. Not a generic chatbot: a real infrastructure tailored to your business.

My method: I analyze your business, identify the most profitable automations, design and integrate the solution into your existing tools (CRM, emails, calendar, Notion, n8n), and deliver a system that runs.

What I develop: autonomous AI agents, workflow automation and orchestration (n8n, Make, API), RAG and conversational assistants, custom connectors, AI-powered CRMs and dashboards.

You can entrust me with the project end-to-end, or we can build it together so your teams can manage it internally. Over 10 structures supported, systems in production. Confidentiality and GDPR respected.
