Simon grew up - in his own words - an army brat, moving around attending 16 schools. He moved to Japan straight out of uni and has lived here for 27 years now. In his years in Japan he has been a rugby referee, managed the local French rugby club for several years, been a club DJ and his latest passion is running and is hoping he can run the Tokyo Marathon once again with the current lottery. In his free time he also has a video blog about weekly news and culture topics in Japan he has been doing for more than 15 years now.

Like everyone else Simon is wrapped up in learning AI and feels very lucky to be in a position to get access to the latest models and tools, and is a trainer of how to use this tech inside Amazon Legal globally, and has given seminars for regulators inside and outside of Japan on the technology.
