## Work Experience
### Senior Software Engineer @ Google
Jan 2021 – Jan 2023 | San Francisco, California, United States
Tech Lead - Frontend Frameworks

I own Looker's build and test systems for frontend code. I provide a tuned, high speed build system including features such as source maps, linting, type checking, multithreading, extensive legacy browser support, and hot module replacement for UI components implemented in heterogenous view frameworks.

I supervised and implemented Looker's transition from our legacy test frameworks Karma, Jasmine, and Cucumber to modern alternatives Jest and Cypress.

I documented first party changes to open source packages and upstreamed them to maintainers, to keep a code base with hundreds of dependencies synchronized with the latest and most secure releases.

Tech Lead - Build Team

I organized a task force for four build system engineers working across the frontend and backend in optimizing CI runtimes, improving the developer onboarding experience, and increasing the verisimilitude of our test environment.

### Software Engineer @ Google
Jan 2020 – Jan 2021 | San Francisco, California, United States
Tech Lead - Unified Routing

I lead a five-engineer team implementing fast "single page application" style transitions across a twelve year old codebase featuring components written in a diversity of frameworks and code styles, including AngularJS and React. I authored a novel library to embed AngularJS and React components within one another at any recursive layering, with dynamic translation of AngularJS data and state management conventions to their React equivalents, and automatically generated type definitions. This library allowed the operation of nested Angular UI Routers with React Router contexts and vice versa, allowing us to accelerate our most common page transitions by a factor of 200% to 600% without rewriting any shipped, battle tested components. I aligned and consolidated multiple duplicate global state containers. I identified and remediated numerous classes of memory leaks to support the application's increased residence time. This achievement was hailed by the team's engineering director as the single most dramatic product-level performance win he had ever seen, saying: "I nearly fell out of my chair".

### Software Engineer @ Looker
Jan 2018 – Jan 2020 | San Francisco Bay Area
Line Engineer - "Looker Boards"

My team prototyped and launched a novel content management system for the Looker Business Intelligence platform, featuring user experience niceties such as drag-and-drop embedded analytics content, inline text editing, and markdown support. We maintained a tight cycle of feedback and iteration by shipping quickly and often, and communicating extensively with early release customers by collaborating with our excellent product management and customer support teams. This pilot was a successful pilot for experimenting with cutting edge open source libraries. This decreased our time to market and paved the way for wider adoption of modern development tools throughout the business.
