Product builder · Generative AI · Centrale Paris

I design, I code and I ship the AI products you imagine.

Fifteen years taming enterprise data. Today, generative AI products — from prompt to deployment.

01

Positioning

Centrale Paris engineer, 15 years at Schneider Electric shipping data products from vision to delivery: scoping (PO/PM), architecture, code, and teams I level up along the way. Since 2025, co-founder of Vikl, an LLM SaaS taken from idea to production. As a freelancer, I turn your vision into a concrete, optimized product, all the way to delivery — I scope, I design, I code, I ship. More than an AI engineer: an end-to-end product builder.

  • Product scoping (PO/PM)
  • Full-stack design & development
  • Delivery & team upskilling
