Role: Machine Learning Engineer
Emoji Scavenger Hunt is a browser-based game built with machine learning technology that uses your phone’s camera and a neural network to try and guess what it’s seeing. This is an example of creative application of "front-end" machine learning running on TensorFlow.js.
Role: Machine Learning & UX Engineer
Gboard Physical Handwriting Version is yet another input device which reads your scribble on your keyboard using machine learning technology. You don't need to remember QWERTY anymore. Just write it.
Role: Project Lead
