About Me
I am an Information Technology professional of 20 years’ experience,
predominantly in the performance engineering/analysis space. I have worked
with many of Australia’s largest organisations, in Melbourne, Sydney, Brisbane,
and in Canada. I am familiar with, and adept, at all aspects of the performance
testing business cycle.
I started my professional working life as a Civil Engineer, before diverting into
being a working musician in Melbourne, interstate, and overseas, for six years. In
1994 I completed a Graduate Diploma in Computing Science at RMIT, and thus
began my IT career. Starting in System Administration and Helpdesk, it veered
into testing via application production support. Knowledge across all architecture
tiers made me well suited to performance-related testing disciplines.
Music is still a hobby and passion, in addition to travel, current affairs and
physical wellbeing. I am also interested in written word, and am probably one of
the few technical people who actually enjoys writing reports.
