Experience

Sabbatical

Mar 2025 - Mar 2026

I took a year off from professional work to rest and explore new ideas (see my blog post to read more). Some of the projects I built:

Slothscript: A scripting language for automation and system administration.
doc-builder: Build and maintain docs from tested external source files.
dhb: An interactive environment for integer arithmetic.

Engineering Lead, Flutter Engineering Productivity

April 2024 - Mar 2025

Flutter is Google's open source, cross-platform application framework allowing a single codebase to target Android, iOS, Windows, macOS, Linux, and the web.

I lead a team that owned three infrastructure services for Flutter maintainers and users:

Infra: continuous integration for Flutter open source pull requests and merged commits.
Releases: ensuring reproducible builds and timely hotfix patches of the Flutter SDK for beta and stable release channels
Devicelab: manage a data center of physical Android, iOS, macOS, Windows and Linux devices that ensure every commit to the Flutter SDK passes an integration test suite across these platforms.

Tech Lead, Flutter Tooling

Nov 2022 - April 2024

Flutter's CLI tool orchestrates Flutter app builds encompassing compilation across Dart for a developer's code along with Java/Kotlin, Objective-C/Swift, C++, or JavaScript for native code. This includes debug-mode builds, involving stateful hot reload of Dart code just in time compiled and release builds ahead of time compiled to machine code.

I lead design review, crash & issue triage, and code review of both full time employees and open source contributors. Features I've built include:

Flutter Preview device, allowing developers to experience Flutter's stateful hot reload without requiring a native build toolchain
Font tree-shaking for the web, reducing the download size of icon fonts by removing code points not referenced from the app
Infrastructure for codesigning pre-compiled binaries that are distributed to end users
