I'm the cofounder and CTO of Ciro (YC S22), an AI agent for B2B sales teams. Before that, I worked on the Kotlin programming language at Google and studied CS at Berkeley and business at Stanford.

This site is a small archive of projects and essays on startups, vegetarian food, technology, books, and the odd internet rabbit hole.
