Tanjeen has a unique talent of being able to explain the most complex networking problems into snackable bite-sized pieces that any non-CS team mate can understand. There have been more than a dozen occasions when I needed to rope him in to tackle consultancy calls. Tanjeen has a knack for strategic decision making that is remarkable.
