We take care of a product called Skan, which is used by internal stakeholders (called fraud agents) to work on all the orders in Klarna that can be fraudolent. This is a story all about how my life got flipped-turned upside down we approached the so called Peak Season (the range of time between the Black Friday and Christmax) and in detail, how we discovered and fixed a bottleneck.
