Kids are either getting smarter or technology has become easier to use. A 15-year-old sophomore at Burlingame High School named Rohan Nath has built a shopping engine that aggregated products from retail sites. The site allows shoppers to browse by a variety of categories like cars, clothes and cutlery, as well as by color, designer or material. It also lets them search from retailers like Sears, Amazon, Macy's or other shops offering the items online. Nath's father, Naren Nath, is CEO at Wayfare Interactive, which develops technology that aims to help advertisers and content publishers improve monetization and revenue.
