Approach

About AI

I embrace AI as part of modern technical work. It lets me explore, prototype, and implement a lot faster, but I keep trying to navigate its advantages and drawbacks in my work.

AI accelerates, judgment stays human

⚠️AI makes producing code and content a lot cheaper but more output doesn't automatically mean better software.

🔧I use AI extensively to prototype and implement faster, but generated output still needs technical judgment, review and testing.

Stay close to the implementation

⚠️Delegating implementation can create distance from the systems we're supposed to understand.

🔧I make sure to spend time understanding the techniques and important code behind what I ship, especially when the goal is also to develop my own technical skills.

Control, profile and verify

⚠️Correct-looking code isn't necessarily correct or efficient, especially in graphics, when it comes to visual results.

🔧I set up a precise context and scope, then rely on profiling, measurement and controlled testing to validate implementation.

Background

Hi I'm Xavier

A tech enthusiast based in France. I’m driven by real-time 3D, spatial computing, and, overall, making graphics work hands-on on the GPU.

Outside production work, I keep building personal projects such as games or XR prototypes.

Aside from work, I'm passionate about tennis, competitive games, motorcycle road trips, and South Korean culture, where I lived for three years.

Let's connect :)
