About Pierre

Do you want to integrate AI into your product but your team lacks the expertise.
Did you test a POC that never made it to production.
You are looking for a senior developer capable of delivering without a 3-month onboarding.
You need someone who delivers, not someone who experiments.

Fullstack developer for over 10 years, from startups to large corporations:
+170 projects delivered in production
+30 clients supported: Chanel, Limova, Nespresso, CNES, OECD, and others

No POCs that stay in a corner. Code that runs in production:
• Scalable and robust web applications delivered from A to Z
• AI agents in your existing applications
• Clean, tested, maintainable, and well-architected code

Whether you need reinforcement or a turnkey project:
1. Team Reinforcement: I integrate into your team and deliver from the first week
2. Fixed Price: I develop your application or your AI component end-to-end

A proven fullstack stack: React, Next.js, Nest, TypeScript.
AI integrated into real projects: agents, RAG, tool calling, MCP.
