My career started in 1975 with the design and specification of electrical
reticulation systems and lighting installations.
Since 1978 I have been designing and developing electronic devices and products
for users which includes the mining industry.
My special interest lies with embedded programming for microcontroller based
devices and analog circuit design.
Software development has fascinated me since first learning to program (in
PL/1) in 1971.
I consider my dedication to solving a problem economically with a meticulous approach, loyalty, honesty and open-mindedness as outstanding characteristics besides standing prepared for any kind of work.
What has made engineering a fulfilling experience during the past is the enjoyment of working creatively, doing prototyping and seeing my innovative and efficient designs becoming practical reality.
