Harry leads the Performance Team at Shopify. His role is making computers go fast while not breaking, and as it turns out, that’s hard. Shopify has an enormous Rails application with traffic that doubles at minimum every year while processing a whole whackload of money for real people running real businesses. This means the problems are hard and the stakes are high. Harry did most of a computer engineering degree at McGill and once won a street race against a Nissan Versa.
