    Software Engineer · -

    In the short time I have been at Twist, I have worked on an amazing team with two other engineers to ship an Android version of Twist's mobile client (previously only available on iOS). The Android client is a non-trivial application built almost entirely using web technologies (HTML, CSS and JavaScript) and packaged for Android with PhoneGap. Working on the underlying application framework has required expert understanding of modern web MV* architecture, and the ability to extend such frameworks to optimize for the web experience on mobile platforms like Android.
