    Bart is hands down one of the best developers I know.
    He's thorough, a fast implementer, great listener, and most importantly an all-around pleasure to work with,
    which is a big consideration when you're working 12 hours a day together.
    Anyone lucky enough to get Bart to accept an offer with them is a very lucky person.
