Developer tools used by other engineers, with public code, research, and demos.
Created by me · Acquired by Sentry
An open-source MCP server and CLI that gives AI agents access to Xcode. Agents can build and run Apple apps, inspect logs, debug, and interact with the simulator.
Its simulator automation builds on AXe. It now gets more than 250,000 npm downloads a month.
Created by me · iOS Simulator automation
A command-line tool to inspect and control iOS simulators. It supports taps, gestures, text input, and screen capture for people, scripts, and AI agents.
LY Corporation's sim-use project began as a fork of AXe, and my Jev + AXe demo passed 100,000 views on X.
Research at Sentry
1,350
AI build runs studied
I published a study of 1,350 AI build runs across three models and three approaches. I used the results to improve XcodeBuildMCP's tool descriptions and session support.
The study found that shell commands with clear project instructions were fastest and cheapest for the measured tasks. It did not measure simulator UI control or debugging.

04Kind words
Recommendations from people I've worked with, across product, research, and engineering.
Cameron is an absolutely brilliant Engineering Manager... he combines deep technical expertise with fearless curiosity, pushing the limits of what our platform can do while keeping customer value front and centre.
Every day he challenges us - and the rest of the team at NOTHS to move faster - think bigger and ship better.
Cameron is an exceptionally knowledgeable engineer who is very generous with his knowledge and time. He is a keen advocate of probing to understand the why behind anything we build.
He is not afraid to ask the hard questions, provide constructive feedback and push everyone to do better.
His pragmatism and perception of the customers needs is excellent and shows through in his work, his participation in planning and in the way he mentors the new and less experienced people around him.
He approaches his work with a genuine desire to make any given project the very best it can be... because of his vast experience and passion for what he does, he achieves it.
He has been one of the most passionate iOS developer I've ever known... truly passionate about crafting impressive UI/UX screens and paying attention to the small details.
It's been a real pleasure working with Cameron at NOTHS. He has a wealth of experience, is insightful, knowledgeable and I have learned so much from him about best practices.
