Between stints at Sprint (which became UUNET which became Verizon Business), where he designed and implemented new Internet products and services, Jeff Fletcher founded Antfarm Networking Technologies, South Africa’s first streaming and webcasting company. He returned to the corporate world in 2004, occupying the corner office of the new product development team at Internet Solutions (then IS). Jeff now works as a Systems Engineer for Cloudera, helping customers build big data infrastructure. In 2012 he founded, a blog dedicated to the art of data visualisation and does occasional presentations for people looking to move beyond pie charts.
