I have worked in media, sport and telecoms sectors at local and international levels since day. I founded Mediacells with Steve to enable global companies to deliver against their digital media strategies.

I am a strategic thinker, skilled at delivering practical routes to market for new products, services and campaigns.

I love collaborations and most recently I’ve been engaged with the Visual and Experience Design department of the University of Applied Sciences in Berlin focussing on future visual designs.

I am solution-oriented, used to developing end-to-end analytics solutions that reveal true insights for our global clients.
