Welcome to the tidyverse with simple visualisations (and a little jittering)
With 34 years’ service at IBM, my core strengths are in boiling down complexity, and developing and articulating a strategy grounded in facts.
My time at “Big Blue” has enabled me to work at scale including, for example, strategic planning for a $2bn-per-year revenue UK services business, and leading a global sales coverage strategy and alignment of 40,000 sellers.
Skilled in exploiting data science for business, I especially like to use R for its flexibility and power. R is an open source language for statistical computing and graphics supported by the R Foundation for Statistical Computing, and is widely used among statisticians and data scientists. To bring my work to life, I create my own graphics with my trusty iPad and Pencil, and occasionally post on R-bloggers.
I post-graduated with an MBA from Hult International Business School in London as valedictorian for 2001. And I live in London.
