PROFILE

Chad Smith

Worked on reliability and platform improvements across Android development projects, focusing on both application startup and debugging workflows. In facebook/buck2 and buck2-prelude, addressed post-install app launch failures by reordering ADB commands, ensuring the debug state was set before installation to prevent boot interruptions and improve CI stability. In swiftlang/llvm-project, enhanced Android LLDB platform support by refactoring for thread safety, introducing AdbSyncService for robust file synchronization, and improving device ID handling. Also stabilized Windows CI by conditionally disabling a problematic test. Leveraged C++, Java, and Shell scripting, demonstrating expertise in build systems, debugging tools, and platform-specific development.

April 2025: Delivered critical reliability improvements for Android app startup post-install across Buck2 projects. By reordering ADB commands to ensure the app is set to debug before installation, both buck2-prelude and buck2 prevent boot interruptions, reducing flaky launches and improving first-run reliability for end users and CI tests. This work involved coordinated changes across two repositories, resulting in a smoother onboarding experience and fewer post-install failures.
