What's been your career highlight so far?

I founded the business of Anti Virus Reseller Limited (AVR) in 2002 on my own at the age of 26. I had some industry experience coupled with all the passion and enthusiasm in the world. In 2004 after nearly running out of money I took on an investor that took 60 per cent of the shares. My career highlight so far has to be buying those shares back in July 2014. Owning 100 per cent of my business again is an amazing feeling!
