Projects Richard has worked on:

Developing A Single Sign-On For The Digital Mailbox
Australia Post had been wanting to unify their digital mailbox sign-in with the rest of their website so that customers could use one log in for both. However, long-running attempts were proving unsuccessful. Richard was able to implement a simple but not obvious solution that leveraged the existing authentication layer and provided a seamless experience for the customer.
Qantas Hotels – Getting Customers The Best Value On Their Frequent Flyer Points
While working at Qantas, Richard was involved in ensuring customers were getting the right results when searching for hotels through their hotel website. He worked on a platform for hotel merchandising via targeted destinations. For example, if customers were looking for the best deals on hotels in San Francisco in the next 3 months, Richard’s team was responsible for ensuring the searches were providing them with the best results possible. The outcome? A cheaper deal for customers and loyal customers for Qantas; a true win-win.
How Updating Weighbridges Saved Visy Recycling Millions Of Dollars
Visy was installing barrier arms at their recycling stations which would ensure the trucks carrying the material to be recycled were actually on the weighbridge, when they both entered and exited. This made sure that the trucks were not off the weighbridge when exiting, otherwise they could have paid for a larger load of recycling. He reprogrammed the weighbridges and was able to test run the software at different recycling stations. The result? A saving of $10 million per year. Not a bad effort at all.
