My name is Edouard, I'm a production engineer in the Rails team at Shopify. One of the many project our team has to work on is keeping our monolith up to date. Before that I was working in the Payments team at Shopify where I was helping to define the future of payments on the web.
Journey of a complex gem upgrade
