Founder, security engineer, and builder in the Bay Area.

Replit

I started coding on Replit in fifth grade. In ninth grade, my Java class used it too. I helped classmates until I became the unofficial second teacher. Years later, I won the Alif x Replit hackathon. I now work at Replit, where I help with abuse and moderation and test platform surfaces for vulnerabilities.

Peak Security

Peak Security is my company. I use AI to do white hat hacking. Peak was a YC Summer Fellow and a Palantir Valley Forge Fellow. It made $40K profit in its first month.

Cerebral Valley

I also worked at Cerebral Valley and AI Valley. At Cerebral Valley, I selected attendees for events, built the mobile app, and built admissions, messaging, judging, and recruiting tools. The work covered 6,000+ builder profiles, 19 AI events, and 3,700+ attendees.

I built Metric with my brother. It helps recruiting teams compare builders using evidence from their work.

Catan Zero

Catan Zero is a reinforcement-learning project for training models to play Catan. I built it with Michael Tan, who is number one in Catan Elo. We met through YC fellows after he showed me a model trained on scraped Catan games.
