02 — About

Between craft and engineering.

I have been building digital products for more than 10 years.

Today I work mainly around artificial intelligence, agents, automation and next generation web experiences.

I also run my own technology lab: AI models, local infrastructure, 3D interfaces, voice, vision and autonomous systems.

My goal: turn new technology into things that are genuinely useful.

03 — What I build

From idea to product.

I turn an idea or a business problem into a working product. From prototype to production.

Artificial intelligence

AI agents, business assistants, RAG, local models, voice and bespoke intelligent systems.

RAGSelf hosted LLMOllamaOpenAIMCPVoice · Vision

SaaS & products

MVPs, web platforms and internal tools built to become real products.

ReactNext.jsPostgreSQLNode

Automation

I connect your tools and automate the repetitive tasks that slow your business down.

Document intelligence

OCR, AI-powered extraction, document workflows and compliance: I turn paper and PDF flows into structured, usable data.

Web experiences

Premium sites, interactive interfaces, WebGL, Three.js and 3D experiences.

Infrastructure

Deployment, hosting, monitoring and architecture so the product actually runs in production.

04 — The lab

I am building my own JARVIS.

Not to make a pretty demo.

To experiment with the technologies that will gradually change the way we work.

Some experiments will stay prototypes. Others will become products.

05 — Projects

Real projects, not concepts.

No fake mockups. Here are products, experiences and systems I have actually built.

06 — Experience

I have built across several worlds.

From the web to physical events. From client projects to my own products.

That range taught me one thing: technology only matters when it works in the real world.

2026

Magic Odyssey

Founded and directed · La Souterraine

An immersive pop culture and medieval fantasy festival. A year of preparation, two sites, 73 attractions, a hundred exhibitors.

2025

Terre d'Impact

Endowment fund · Roland-Garros

Design, build, then hosting in house. It runs on my own infrastructure.

Via Luminis

Site & launch

From the first mockup to a domain that answers.

2024

3D Virtual Tours

Company founded and run alone

Company created and run alone: the offer, the 3D production, the sales, the paperwork.

Before

Amazon & Monster Energy

Flow, events, product

Flow management for Amazon, an event partnership with Monster Energy Europe. WordPress plugins published on CodeCanyon.

07 — Method

One idea. One problem. One product.

01 — Understand

We identify the problem, the user and the outcome expected.

02 — Design

I define the experience, the technologies and the architecture needed.

03 — Build

The product is developed and tested in real conditions.

04 — Automate

Repetitive tasks become workflows and agents.

05 — Deploy

The product goes to production on the right infrastructure.

06 — Improve

We measure, simplify and optimize.

No complicated method to look serious. We start from a problem and build the solution.

08 — Booking

Got an idea? Let's talk.

Next generation site, SaaS, AI agent, automation or an experimental project. 30 minutes to understand your project and see what we can actually build.

  • Free video call.
  • French or English.
  • A first read on the project.
  • Possible technologies and approach.
  • An estimate of scope and next steps.

If I am not the right person for the project, I will tell you.
