The HDI project is a commercialization of a research product. It has been developed with a strong software methodology with the focus on the client. It has been sold to hospitals and institutes within the health sector, such as the Baker Heart Institute and Queensland Health.

HDI is an application to link patient data between different and remote databases without revealing personal information. It is used by researchers for projects such as cancer studies. It is a client-server application with a Java Swing GUI frontend and a JBoss server backend.

My role on this project was to develop both server and client ends of the application, extending the domain model and building new client screens.

Smart Practice is a practice management solution for the accounting industry. It is a web hosted solution built on an AJAX/Java platform. Its web front end is an advanced AJAX desktop/dashboard with drag and drop applications. It uses the Yahoo! User Interface (YUI) and remotes the service layer using Direct Web Remoting (DWR).

I was the lead developer on this project.

The MERLIN Spatial Information Enquiry System is a web based Java based Geospatial Information System. It is used to manage NRMWs spatial mining and resource information. It harnesses an advanced Web 2.0/AJAX frontend and backends on to ESRI's ArcSDE/ArcIMS GIS software.

My role on this project was to implement the system requirements across all layers of the architecture. This included developing the persistence layer and database schema, developing service objects, developing struts actions, developing a rich Javascript/AJAX based user interface which included floating windows and wizards, enhancing the JSON framework for the data transfer, writing JUnit test and writing end user documentation.

Quotient is an advanced, flexible system for the real time measuring, accounting and quota enforcing of Internet traffic, developed in house at The University of Queensland. Quotient performs per user billing and tracks which IP addresses a user has used. It implements a unique concept of quota pools, which allows a user to be billing to multiple departments. It handles more than 30,000 concurrent connections. Quotient has enabled departments to save money through managing their Internet usage.

The Quotient product has been so successful that it is was marketed to other Australian and overseas Universities. It has been sold to La Trobe University and has had strong interest from The University of New South Wales, The University of Southern Queensland and Edith Cowan University.

My role on this project was chief architect, developer and implementer. I was nominated for The University of Queensland's Pride in Work Award for my work on Quotient.

WebPrism is a web-based central services management system.

In this project I built a high speed netflow processing tool. The purpose was to account and monitor all Internet activity giving detailed reports on networks, ports and protocols. This project was written in Perl and C to enhance performance. I developed a custom netflow collector that allowed for significant compression to the data that was being collected. This was built for Cisco routers and captured data for over 60,000 IP addresses.

In my work for UQconnect - The University of Queensland's commercial Internet Service Provider, I have developed systems for the provision of its Internet services such as the infrastructure for the authentication and accounting of its broadband, wireless and dial up services. I have also developed websites where users can access their account details. UQconnect services 35,000+ students, 7000 staff and 8000 commercial clients.
