During my working life I started out as a Production Engineer for the first ten years or so. Worked for an automobile maker in Sydney (I worked on the infamous P-76!) and other engineering companies.
Moved to Canberra and was employed by the Australian Government for thirty years. Moved from engineering into computing and worked my way up the "greasy poll" to become a senior manager with responsibilities for systems development and support. In retirement I build and support websites for not-for-profit organisations.
