For 20 years I worked as a Software Support Manager for Goal Systems International, moving from Johannesburg, to London, Paris and Sydney. My responsibilities were to "sales engineer" teh sale of high end software (over 100K) to major clients across South Africa, Europe and Australasia. I have presented and negotiated with senior executives and technical managers in most major financial institutions and leading companies in those locations.
From there I developed a freelance software development career designing and developing software with Commbank, Warman International, Quicken Australia amongst other clients.
