I'm a data scientist, an engineer, and an ecommerce entrepreneur. I am also an author, speaker, and (sometimes) brand evangelist. I authored Data Science for Dummies (03/2015) and am currently working on Big Data for Dummies - Dell Edition (07/2015) for Wiley publishers. I speak on the topics of big data, data science, and analytics. I have spoken across 3 continents, 3 countries, and 9 different cities thus far. I speak at events as large as SXSW Interactive 2015, and as small as Chiang Mai University's Annual R User Conference. I'm experienced with speaking for and representing organizations as large and dynamic as National Geographic Channel and IBM.
