New York, United States
Summary
🤩
Rockstar🎓
Top SchoolLeonard Grey is a seasoned software engineer with 13 years of experience building macOS and iOS tooling and infrastructure, currently working on the Swift toolchain at The Browser Company in New York. He spent over a decade at Google contributing to Chrome for Mac and toolchain work, and earlier built infrastructure and product features across startups and Artsy. Leonard has deep low-level expertise in crash-reporting and debugging systems—contributions to prominent open-source projects like Breakpad, Crashpad, and Chromium show he’s comfortable fixing architecture-specific bugs (including ARM64/macOS nuances), improving diagnostics, and hardening test suites. He blends front-end UX changes with backend reliability work, from sharing UI features in Chromium to modernizing Objective-C components and test automation. Colleagues rely on him for pragmatic solutions to platform-specific problems and for navigating the weird edges of OS behavior that most engineers rarely touch.
