I led technical discussions and engineered custom product builder of the 3rd-gen web-to-print platform that powers Staples Copy & Print and other well-known retailers (which I won't name here). The product builder is what allows users to personalize stationery items and make them unique on web in the comfort of their home. It is the cake of the web-to-print platform.
This platform successfully replaced an older system that generated about approx. 100 million dollars in revenue, and it launched in January 2016. It continues steady growth in the market with increasing revenues.
