John Dunning is a Senior Engineering Manager at Shopify. He possess expertise in embedded systems, linux, distributed systems, cloud computing, c and 19 more skills. Colleagues describe him as "John can solve difficult technical tasks with quality solutions that are maintainable. I inherited some of his work and found it to be clearly coded and well crafted. As a manager John excels in communicating with his group of engineers and keeping clear priorities." and "John is a real "get it done" kind of guy, able to solve extremely difficult problems quickly and yet without sacrificing quality. I inherited one such solution, so I know it intimately, and found that John's work stood the test of time, requiring far less maintenance than would generally be expected in such a difficult problem domain. As a peer and as a manager, he demonstrated a very high level of diligence and maturity, and inspired those qualities in others as well. John was more often than not the first person I'd consult when I was wrestling with a problem, and I'd welcome the opportunity to work with him again."
