Being a Theoretical Physics graduate, Jevon was exposed to different ways of dealing with large amounts of data using programming languages over the course of his degree such as Python and Java. Being able to see patterns and trends within data sets sparked an interest within all things data. Coming across Tableau in an email, Jevon was amazed with how easily and effectively Tableau dealt with data, and soon developed a great passion in making sense of data using Tableau.
Outside of work Jevon likes to keep himself healthy by playing range of sports such as Tennis, Football and rock climbing.
