Already engaged in a number of web-based maintenance projects with Walmart, we were asked to replace their existing outsourced developer and assume responsibility for the ongoing support of their native mobile apps, which were fully integrated into Salesforce Commerce Cloud. Over the fifteen months, we undertook 6 application updates related to Salesforce CC technology changes, and 3 major development projects related to (a) new marketing initiatives, (b) new cart / checkout process, and (c) international currencies.
