Not to take any credit away from Jan, it is however worth noting that his background (and that of many of the early employees) is in Infrastructure / Backend at Yahoo! The side-effect of that is that reliability/uptime is already in his DNA, as also, just "getting things done without enjoying any of the limelight", and he's done a great job carrying over lessons/behaviors learnt in that previous life over to WhatsApp.
