Pronounced Joe-ahn — a male name in France.
Parisian software engineer, splitting time between Paris, France and Monterey, California. Twenty-plus years designing and shipping AI and software systems for enterprise clients.
Today I run Fog&Frog, a Franco-American AI & software consultancy I co-founded with Kelly Clark, where I lead Engineering & AI. We help mid-market and enterprise teams turn complex AI and digital challenges into clear, reliable systems — from AI adoption to legacy modernization, taking full accountability for outcomes.
- 🏛️ Software architecture — the core of my work; designing systems that scale, evolve, and don't collapse under their own weight
- 🧪 AI research — model evaluation, fine-tuning, retrieval, novel architectures
- 🤖 Applied AI — agents, LLM-powered tooling, production-grade systems
- ☁️ Cloud architecture & legacy modernization
- 🛠️ Custom business systems and knowledge platforms
- 🏔️ Off the keyboard: mountaineering in the Pyrénées and photography
