CTO & AI Agent Architect: I transform your business processes into reliable automated systems
I industrialize AI agents (LLMs) that handle business tasks: lead qualification, document generation, support, sales, data. From POC to production, I design systems that run 24/7, are reliable and maintainable, not just demos.
Over 13 years of experience, including a role in the CODIR of Les Ripeurs (scale-up with €40M cumulative revenue in 7 years), where I managed technology and deployed over 350 Make and n8n automations, integrated with code and business applications. There, I designed an AI agent that receives and qualifies quote requests: it asks for missing information, generates the quote, or escalates to a human.
In parallel, I designed the end-to-end LLM architecture for Lumeet, a real-time conversational analysis AI co-pilot for sales teams (objection detection, suggestions). This dual technical and product expertise allows me to understand your business challenges as well as the stack that serves them.
What I do concretely:
- Design and deployment of AI agents and RAG (Claude, GPT, Gemini, Mistral) for productivity, sales, support, or data
- Orchestration of complex automated systems: n8n, Make, business API integrations (Zoho CRM, Airtable, Stripe Connect…)
- Full-stack development: Node.js, TypeScript, Angular, MongoDB, serverless and microservices architectures
- Creation and scaling of SaaS platforms
- Securing APIs and applications, support as a CTO or technical right-hand man
Why me:I cover the entire chain, from business framing to AI agent in production, without handoffs between a strategist and an executor. You talk to one person who understands the need, designs the architecture, and delivers. My goal: transform your ideas into concrete, secure, and scalable solutions.
