Hi, I'm Josh. I'm a software engineer, skier and photographer.
I'm currently building Swarm , an AI IDE.
Previously, I built Uber's load testing system, Hailstorm . I was an engineering manager at Gem . And most recently I was cofounder of Engines , building a repo setup agent.
You can find my Substack here .
This blog is a collection of my notes on software engineering, startups and AI coding:
