Back to original languageAbout Etienne
AI Architect & Fractional CTO | SaaS, Cloud-Native & Voice Agents Expert
About Me: CTO and Cloud Architect with 15 years of experience, I operate at the intersection of product vision and technical excellence. I support startups and IT departments that cannot afford to fail their scaling or AI integration.
My approach is pragmatic: an architecture is only valuable if it serves business profitability.
MY 3 PILLARS OF INTERVENTION:
🚀 Cloud & DevOps Architecture (AWS / Kubernetes) I transform your POCs into industrial platforms. I led the transition of custom solutions to scalable SaaS models, reducing production costs while handling peaks of 50,000 users. I secure your deployments (CI/CD, Docker, Scaleway).
🤖 Generative AI & Voice Agents (GenAI Expert) Beyond the hype, I master deep AI engineering. I am the creator of Stimm, an Open Source platform for ultra-low latency voice agents (<500ms).
Know-how: Python/FastAPI Orchestration, complex RAG, WebRTC optimization (LiveKit), and SIP telephony management.
📱 IoT & Phygital With my experience at JCDecaux and Printemps Haussmann, I know how to manage real-world constraints: indoor geolocation, hardware, and unstable networks.
WHY ME?
Fractional CTO: I structure your tech team and your roadmap (Rennes or Full Remote).
Hands-on: I code the critical components that your teams don't yet master.
Open Source: I actively contribute to the AI ecosystem (Permanent technical watch).
Let's discuss your architecture challenges or your next AI project.
