Member since November 2, 2015
An engineer with a right-brain-hemisphere orientation (a unique combo), Patrick is good with lateral thinking, visual problem solving, green-hat thinking as well as the analytical reasoning that engineers typically rely on. He has a decade of professional experience, recently in front-end web tech (React.js, Redux, ES.Next, Webpack, Angular, Backbone.js, and jQuery). He's currently learning about the psychological foundations of UI design theory.
Patrick is now available for hire
