I’m an creative-thinking innovator with an ability to get real systems working in an optimal way. I enjoy the elegance associated with simple, yet optimal, solutions to complex problems. I’m simultaneously perfectionistic and pragmatic -- aware that sometimes the optimal solution is the one which can be implemented quickly. I’m happy working alone or leading a group, but happiest when learning from my peers. I’ve got good teamwork and communications skills, but detest first-person personal pronouns. I’ve got a track record of engineering and building systems like solar powered cars and algorithmic trading solutions which are more efficient, run faster, and are implemented more quickly than the competition.

Selected Porfolio

For a (more) complete portfolio of projects, please see

  1. I-Box -- The I-Box is a device designed to process digital video in real-time, for use in digital surveillance systems. The device annotates analogue video, and as such can be retrofitted into existing It uses a high-performance 32-bit processor (PXA270) coupled with various peripherals to interface with an Ethernet network, MPEG4 encoder/decode IC, video capture IC, video output IC, and custom-built overlay electronics. The device was bound by strict cost, power and time-to-market requirements. My

  2. UNSW solar powered car (Sunswift II, III and IV) -- Sunswift IV won the silicon class of the World Solar Challenge in 2009 and is currently the Guiness World Record holder as the world’s fastest purely solar powered car. I was involved with parts of the mechanical design, and was responsible for most of the electronic and electrical design. I designed and built the dozens of devices including many for the car’s telemetry and control system, >99% efficient maximum power point trackers, and a multitude of other critical components. I also built various mechanical components, usually using aircraft-grade carbon composite materials. I mentored younger team members, teaching many about practical electronics design and implementation.

  3. Power management PhD thesis -- Koala was the basis of my PhD thesis, being a method for automatically managing the myriad of power management settings available to a modern operating system. By using models of the system to predict the effect of different candidate settings, my method is able to effectively balance power consumption and performance to choose the lowest energy for the highest performance. It was implemented in Linux and in some cases shown to reduce the dynamic power consumption of a computer by nearly half for a very minor (<5%) performance detriment.

  4. Zomojo’s trading systems -- Zomojo is a small hedge fund specialising in low-latency arbitrage. During my time at Zomojo I was instrumental in improving the performance of our systems by a substantial amount. Given this was already a reasonably well-optimised system, it was no mean feat. Confidentiality prevents publication of the details.
