We worked on Tests, developer tools, and public test-running infrastructure for the JavaScript programming language.
We work to maintain and improve Ecma Test262, the canonical specification conformance test suite for JavaScript the programming language. We contribute tests for new features, manage ECMAScript specification changes, support contributors with reviews, maintain the overall suite as new tests are submitted, and work on tools surrounding the tests for JavaScript engine teams.

Embedding Scratch in an Arm-based single board computer using Electron, React and Scratch 3.0.
We spent 2.5 years in production with the team at [Joylabz](https://joylabz.com/) leading up to the Kickstarter product launch in May 2019. We developed the architecture, deployment pipeline and lead the engineering implementation for this embedded web browser based Scratch 3.0 video game console. Now that the Kickstarter has launched, we are working on the manufacturing pipeline and some exciting yet-to-be-announced add-ons for the product!
