Staff Engineer at Shopify (building Shop app), improving mobile reliability, performance, developer workflows, and agentic coding. By integrating multi-agent orchestration, I focus on high-leverage engineering and cross-team impact. Former Technologist at the Sovereign Tech Fund supporting critical OSS infrastructure, and previously Senior Software Engineer at Microsoft driving React Native adoption and shipping features across Outlook, Teams, and Office.
From 2018–2024 I served as a React Native core maintainer, leading 20+ releases and coordinating efforts across companies. These days my OSS time is limited—I contribute occasionally and mentor maintainers—while my primary focus is Shopify.
A few things I’ve worked on as an engineer and maintainer:
- React Native, a framework that enables building cross-platform iOS and Android apps with JavaScript.
- React Native Windows, bringing React Native to Windows.
- React Native macOS, bringing React Native to macOS.
- rnx-kit, tooling from Microsoft to improve React Native developer experience.
- React Native Test App, a multi-platform RN host app that minimizes upgrade pain.
- rn-full-pack, an opinionated VS Code extension pack for React Native.
- Agents Party, an open-source themed agent orchestrator scaffolder. Silly little personal project.
Beyond code:
- debug:mind, a YouTube series and resource hub about mental health in tech.
- Talks, podcasts, and more, a list of conference talks, posts, and recordings.
- Job Hunting Resources, links and notes to help folks find roles in tech.
