Builder and AI Engineer. I'm a teenager, and I've shipped AI companions that hundreds of thousands of people talk to every day and startups that convinced investors to write checks. What I care about is the harder question underneath all of it: how the universe actually works.

Public projects
- AI Roleplay Bench — AI models are often measured by the answers they get right. Roleplay asks a different question: how well can they carry a character and a conversation? I started AI Roleplay Bench to focus on that question — an independent benchmark for AI roleplay. I build and run it myself, from the benchmark to the public site. Explore the benchmark.
