Staff Engineer at AXA France, specialized in front-end development, I aim to solve problems before they even arise!
Passionate about new technologies and debate, I host the podcast "C'est Pas Le Sujet" ("That’s Not the Point").
I constantly try to share my knowledge and challenge it by speaking at numerous events (keynotes, conferences, meetups, etc.) and teaching in several engineering schools.

Let the Code Vibes: Should We Write for Humans or Agents ?

What if the code we write for humans is actually slowing down our AI?

In this session, we’ll explore a radical idea: code doesn’t need to be readable—it needs to be efficient. Using the same application, I’ll show you:
- A human-friendly version, with clear structure, comments, and best practices.
- An AI-optimized version, where performance for users and ease of modification by LLMs are the only priorities (no more ‘pretty code’).

We’ll compare metrics like execution speed, memory usage, and—controversially—how easily an AI can extend the code. And we’ll debate: Are we writing code for the past (humans) or the future (AI)?

The main goal is to create interrogation about our anthropomorphic way of writing code with AI. We try to ask IA to write code for IA ... Is it the most optimised way to write code in 2026 or it's just a way to stuck us in our confort zone and avoir to lose what define us as humans : our intelligence ?

Are we still designing for Humans ? The future of front-end in the Age of Autonomous Agent

The front-end has always been about Humans, visual interfaces and UI/UX flows. But what happens, when the primary "users" of the web are no longer humans, but autonomous AI agents ?

With the rise of emerging protocols like MCP, enabling AI agents to navigate, interpret, and act on the web independently, we are facing a radical shift. Will traditional interfaces become obsolete ? Will front-end devs pivot from crafting user experiences to designing machine-readable endpoints ? Are APIs the new UI ?

In this presentation, we will explore what the future might hold for front-end developers when your user is no longer a person - but a machine acting on behalf of one. We will dive into the implications of agent-first design, the evolving role of UI/UX and what developers can do to stay ahead.
