Major Achievements

Making Bazel universally adoptable.

Founded Aspect.build, a premier services and SaaS company in Developer Tooling.
Host the Aspect Insights podcast about Bazel and its ecosystem.
Brought the Bazel conference and technical projects to Linux Foundation.
Authored or co-authored many language extensions, including JavaScript/TypeScript, Docker/OCI, as well as utilities such as tar.
Organize and lead the community, mentor contributors and steer evolution and design.
Supporting thousands of users including dozens of large enterprises.

Created Error Prone.

A static analysis plugin for the Java compiler that detects many classes of programming mistakes.
Rolled out stricter compiler across Google monorepo by creating a MapReduce framework that runs the compiler in “fix mode” across all compilations.
This effort became a staffed team, has over 600 checks and has prevented thousands of bugs including severe production outages.

Angular CLI Tech Lead

Founding member of team to make TypeScript an official Google language and wired Angular development into Google’s toolchain.

Angular

Tech Lead for Angular CLI and Tooling (1.5M users).

Led DevInfra work such as syncing code changes between GitHub and Google-internal repo.

Converted Angular itself to TypeScript.

Migrated Angular to Build&Test with Bazel, along with its ecosystem (Material components, ngrx, Angular Universal). 87% reduction in Angular’s CI latency.

TypeScript

Founding member of team that implemented TypeScript as a supported language in Google. Wrote Bazel integrations, tooling for making TypeScript edits across the entire monorepo. Implemented tslint across Google’s code, built into code review tool.

Wrote third-party strictness checker to build into the TypeScript compiler, https://tsetse.info. This is modelled on my very successful project Error Prone which does the same for Java.

Google-wide continuous integration (TAP)

This is Google’s CI, based on running Bazel and Remote Build Execution on a massive cluster. Led the migration of project definitions to a Maven-like format, improved team processes and testing practices.

Tech Lead for two years.

Bazel Results UI (Sponge)

This service automatically injests event data from all Bazel executions and presents results in a GUI. Allows more intuitive comprehension of build and test failures, troubleshooting slow builds, sharing permalink when requesting help.

Tech Lead for one year.

Opower, 1 year

As employee #2 I got to build the UI for the company’s flagship “Home energy reports” product. This was rendered onto paper and served by the US Postal Service! The company was later acquired by Oracle for $50M
