Yehuda is a True Believer in the power of the open web, especially when the web evolves as a collaboration between browser vendors, framework authors and application developers.

He is one of the creators of Ember.js, and a retired member of the Rust , the Ruby on Rails and jQuery Core Teams. He is an occasional member of ECMAScript's TC39 standards committee, and a former member of the W3C's TAG (Technical Architecture Group).

He was the co-author of the Extensible Web Manifesto, of which he is still very proud.

His 9-to-5 home is at his first true technical love, Heroku. There he architects Heroku's front-end. He is currently working on standardizing Heroku's front-end stack around Ember.js, and helps to maintain Heroku's flagship Ember app, the Heroku Dashboard.

Previously, he spent a decade at Tilde, a company he founded. He worked there on Skylight, the smart profiler for Rails.

He's best known for his open source work, which also includes having created projects like Handlebars, Bundler and Cargo.

He formerly traveled the world doing open source evangelism and web standards work, and is not a merely occasional traveler. He continues to evangelize Open Source and standardization online.

He can be found on Twitter as @wycats, @wycats.bsky.social on Bluesky, and @wycats on Threads.
