About me

Harnessing the power of technology
for positive business and social impact…


From a young age, technology has been an important part of my life and I was fortunate enough to get one of the first Sinclair ZX Spectrums in the UK when I was young, and have always enjoyed using and playing around with computers. 

That passion for technology has led to me working for some of the world’s top tech companies, and for some well known brands where I have been a product and technology leader.

I am Chief Digital Officer for T-Mobile, delivering an advanced 4G LTE and transformative nationwide 5G network that offers reliable connectivity for all.

In this role I am responsible for driving T-Mobile’s digital strategy, and you can find out more about my career and download a full biography below.
