Software Developer Dotric Pty Ltd

Doug graduated from Deakin University Geelong, Victoria, Australia with a Bachelor of Engineering.

Early in his career, Doug worked on an automated system for testing telephone lines. This system used a network of DEC PDP11s. The software was written in Oregon Pascal with an event driven structure. This early involvement in event driven structures proved to be an invaluable stepping stone into Windows programming some years latter.

Doug completed a Graduate Diploma in Education at La Trobe University to become a qualified secondary school Mathematics and Physics teacher. Subsequent IT contracts were with universities. One such contract was to add functionality to MSN Messenger.

In recent times Doug has been working on database and Android applications.
