Hi, I'm Justin! 👋

I'm very excited and very worried about the potential of AI, which is why I worked at Anthropic PBC, where I was involved in developing and launching the Model Context Protocol.

Previously, I worked at various other companies—notably Meta and GitHub—and have done some independent consulting as well.

In a past life, I contributed significantly to some open source projects in the iOS and macOS ecosystem:

• ReactiveCocoa: reactive programming in Swift and Objective-C
• Mantle: a model framework for Cocoa
• Squirrel: robust software update framework for Mac apps
• Carthage: a decentralized dependency manager

I may not be able to respond to pings and reachouts—sorry in advance.
