Professional background

Professional background

My experience spans across technology, telecoms, financial services and online business.  I have particular expertise in network infrastructure projects, IT and business process outsourcing, data centres, telecoms regulation and cybersecurity.

Much of my focus is on helping clients get deals done in markets subject to an ever-expanding web of regulation and in respect of new technologies or services. I have a reputation of handling high value 'bet the business' projects and the value of some of the deals on which I advise extends into the billions.

I am recognised as an expert in Chambers, which says: “He thinks outside the box and delivers in-depth, practical support”. I have also been described as “a top-quality lawyer with a sharp commercial mind”, "approachable and proactive" and "very client focussed".

I regularly write and speak about emerging legal issues and I am particularly interested in the effects of digital disruption in today's marketplace. 

In my spare time I enjoy raising two young boys, doing my best to pass on my interest in rugby, cricket and percussion.
