Meet the Team

image128

An award-winning Australian team of software engineers and developers

We are essentially the core development team members of PTIPS: the world-leading and award-winning Intelligent Transport System that tracks every bus in NSW with GPS in order to provide on-time running reports for the state government, automatically request green lights for late running buses, and generate the bus stop arrival data that powers apps like TripView. 


We have applied our unique expertise to the challenge of automating Contact Tracing in pandemics. 

Our team has 180 years of combined ICT and Clinical Drug Trials experience.
