Freelancer profile translated to English.

Description

CTO of a studio and freelance developer, 15 years of software production. I design and deliver custom AI systems and business tools: custom production code, not no-code or prototypes.

What I build:

→ Production AI Multi-Agent Systems

Pipelines orchestrating a team of specialized agents, with human validation, strict audit trails, and budget control. Concrete result: an editorial research process of 4+ hours reduced to 45 minutes.

→ Complete Business Platforms

Full-stack internal tools that replace SaaS stacks. Latest project: a 6-module platform (financial modeling, design collaboration, AI knowledge base, investor reporting).

→ Custom AI Infrastructure

RAG with fact-checking, multi-model orchestration, cost optimization (light/frontier model routing), real-time data pipelines. Where Make, n8n, or Zapier reach their limits: real code, tested, documented, maintainable.

Stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, Redis, AI agents (OpenAI, Anthropic), Drizzle ORM, Docker.

I've delivered for AXA, Thales, Crédit Agricole (Pacifica), Karl Lagerfeld, Action Logement, Korian: environments where systems cannot fail and where CIOs scrutinize everything.

Native French/English bilingual. Clients in France and internationally, full remote from Toulouse.
