Today we’re joined by Andrew Guldman, VP of Product Engineering and Research and Development at Fluid. Andrew and I caught up a while back to discuss Fluid XPS, a user experience built to help the casual shopper decide on the best product choices during online retail interactions. While XPS has expanded since we recorded this interview, we specifically discuss its origins as a product to assist outerwear retailer The North Face. In our conversation, we discuss their use of heat-sink algorithms and graph databases, and their use of chat and other interfaces, and the challenges associated with staying on top of a constantly changing technology landscape. This was a fun interview! Thanks to Pegasystems for sponsoring today's show!
