Echosim is a web-based Amazon Echo simulator. The simulator enables anyone with an internet connection to talk to Alexa. Previously only people in the US who owned an Echo device could talk to Alexa.
I initiated and led the design and development of Echosim while at Amazon. Shortly after launching the website, journalists started writing about it. It got so much press that it was the #1 trending item on Facebook.
Echosim became an essential testing tool for developers. Devs across the world used the simulator to test the Alexa skills they made. Without it, most of the world would not have been able to build skills.
