Blake West
They're my professor  •  Founder, Teacher @ LessonUp. Co-inventor of Hummingbird notation. Former pro musician. Wharton '09. Love music, learning, reading.
Ari is a true expert in app development, on both the front and back end. He knows Angularjs inside and out (as in, he literally wrote a book ... on it), and has always been eager to help others learn. I worked with him at Hack Reactor (the premier school for learning advanced JavaScript), and as a teacher, he's always generous with his time for the students. He sits down next to them, and works through their issues, explaining concepts as he goes. Hack Reactor has been lucky to count him among their instructors.
