Hi, I'm Antoine.
I hunt bad bots for a living.

I’ve been working on device fingerprinting and bot detection for about ten years. I started with a PhD focused on browser fingerprinting, its impact on privacy, and its use in web security. I then moved to industry, spending five years at DataDome as VP of Research, where I worked on device fingerprinting, behavioral analysis, proxy detection, and large-scale bot detection across high-traffic websites and mobile applications. Since the end of 2024, I’ve been leading the research team at Castle, working on both bot and fraud detection.

You can find my latest writing on the Castle blog.
