Roblox
This chapter is still being written, so I'll keep it short and resist the urge to narrate a story whose ending I don't know yet.
In 2025 I joined Roblox to build content understanding and moderation AI. The pull was simple once I saw it: I had spent years teaching machines to read content, and Roblox has the hardest content I know of — millions of games and experiences that you cannot fully understand without playing them. The understanding models feed everything the platform does, from moderation and brand suitability to discovery and ranking; moderation just happens to be where a wrong answer costs the most, on a platform where so many of the users are kids.
The stretch I am most excited about is in-game understanding — putting agents inside the same sandbox the experiences run in, letting them explore and collect artifacts, and distilling what they find into experience understanding records the rest of the platform can build on. I've written that up properly on the work page and in my research notes.
Check back. The good anecdotes need a few more years before they're safe to tell.
