Surgeonline is a web-based system to relieve surgeons and surgical assistants of the burdens of billing in the Australian health system. With over 8000 surgeons Australia-wide utilising our services, Surgeonline is recognised as Australia's largest medical billing agency of any kind. We focus on security, accuracy and simplicity. Meanwhile our clients reap the benefits of automated registration, sophisticated billing calculations, fast payment turnaround times, detailed financial accounting and above all, countless hours of time saved in practice administration.Automation is the key to scalability in an industry mired down in paperwork. Surgeonline takes advantage of existing electronic distribution channels and works with health funds and insurance agents to establish new automated electronic links. The result is a drastic reduction in cost, data entry errors and payment turnaround times. Ultimately, technical expertise honed in cutting edge sectors of the computer engineering industry has been used to revolutionise billing and practice administration in the health industry.

Integrated Blackmagic's hardware with the host operating system and third party applications. Primarily worked on video codecs, PCI drivers, embedded devices, h.264 encoding, stand-alone applications and tools. The focus was always on design, high performance and a seamless end-user experience.

Hired with the team from Adacel Systems in 2003, our work on the Mac OS X port of CXFS continued inside SGI. Building kernel-level file system software at a time when Mac OS X was evolving rapidly, I was responsible for the port as the project's technical lead.Interacted directly with many Apple engineers, both over email and in person at San Francisco Worldwide Developer Conferences (WWDCs) from 2003-2006 and a kernel developer kitchen at Apple's Cupertino campus in 2005. Apple was in the process of establishing its Kernel Programming Interfaces for Mac OS X 10.4 Tiger and the needs of an in-kernel clustered file system necessitated us working closely with them to ensure our product could co-exist in their new environment.Fielded technical support issues and escalations, assisted marketing, sales and system integration engineers with SAN installations.Following an internal reorganisation of engineering projects, I worked on Linux XFS and automated RAID configuration tools. One example of this was adding support for file streams to the XFS file system to enable multiple telecine systems to write movie frame files to a file system concurrently in separate contiguous locations on disk. As part of this work I wrote the xfs_filestream and xfs_mru_cache code in the Linux kernel.

Hired from overseas as an Apple Macintosh software specialist, my position at Adacel involved porting Silicon Graphics' CXFS clustered file system to Mac OS X. Together with a small team of engineers, this project was built from the ground up at a time when the Darwin kernel at the core of Mac OS X was still evolving rapidly. Six months into the project, the team was hired into SGI directly to continue their work.

Worked on scalable wavelet video codecs, QuickTime integration, PCI video capture card drivers and embedded Hitachi microprocessor software for rack-mount video servers.Ported the existing video caching products to Mac OS 9 and Mac OS X, including a substantial C++ codebase and inter-process communication with active QuickTime codecs.Re-designed the product user interfaces and produced all product documentation. Interacted directly with Apple engineers to solve complex issues with the low-level behaviour of Mac OS 9 multitasking and the QuickTime frameworks.Demonstrated IPV's new products at the National Association of Broadcasters (NAB) conference in Las Vegas and IBC Amsterdam, consulting with existing and prospective customers to discuss solving their video workflow problems.

Wrote Macintosh hosted client-server telephone provisioning software that's still in use by thousands of users in Australia's second largest telecommunications company.Responsible for the entire client-side C++ codebase, I developed the software with extensive consultation with the client in both Melbourne and Sydney.
