Tech entrepreneur, commercial pilot, international consultant, author and lifelong adventurer.
My professional journey began with mainframe computers in South Africa in 1983.
Since then, I’ve worked across multiple industries and continents, founded businesses, explored emerging technologies and pursued opportunities that rarely fitted into a conventional career plan.
More than four decades later, I’m still learning, experimenting and creating.
Present Day
RapidSky Aviation Solutions
2023–Present | Chief Executive Officer
As a pilot, my thoughts are seldom far from the sky.
RapidSky combines my experience in aviation, technology and entrepreneurship to develop practical solutions for general aviation.
Our interests encompass aircraft development, aviation technology, engineering solutions and specialist operations, including humanitarian and animal welfare initiatives.
After more than four decades in business, I’ve discovered that starting another career can be considerably more enjoyable than retiring from the previous one.
ZaGenie
2004–Present | Chief Executive Officer and Technology Consultant
ZaGenie brings together decades of information technology experience, accumulated intellectual property and a carefully refined collection of tools, systems and workflows.
As a boutique managed services provider, we support a select clientele with technology consultancy, systems integration and managed IT services.
My philosophy remains straightforward: explore emerging technologies, test them thoroughly and implement what genuinely improves productivity.
We live on the bleeding edge of technology so our clients don’t have to.
Ubuntu Synergy
Ongoing | Founder and Initiative Developer
Growing up in Africa gave me an appreciation of ubuntu: I am because we are.
Ubuntu Synergy applies that philosophy to a growing ecosystem of 47 initiatives combining education, entrepreneurship, income opportunities, community development, conservation and practical assistance.
The objective is to empower people through collaboration and sustainable participation rather than dependency on traditional charity.
