Employment History

    President, Digital Design Inc. (US registered company) Apr 2005 to Present

Responsible for all technical and administrative functions, as well as software development,

    systems administration, and IT management.

Maintained and evolved the websites for my software products (see below).

    Maintained and evolved the supporting Linux servers, and VPNs in both the United States and New Zealand.

    Built an Asterisk PBX running on a Linux platform, using SIP and IAX devices on the VPN, and interfaced to my business phone numbers via Broadvoice.

    Evolved the supporting software for my software products into a fully modular e-Business tool suite, built in C++ and running on Linux servers. The system automatically performs all

    business functions; sales, online payment processing, and generation of invoices / receipts /

    credits, managing customer accounts, periodic rebilling for subscriptions, right through to

    generating the daily import files for QuickBooks.

Developed software for internet download websites. C++ running on Linux/Apache. The

    system is fully automated, with the customers being able to make single purchases, or charge

    multiple downloads to their credit cards.

    Developed PC based entertainment / marketing software under the name of Musical Vision. This combines animated sequences of images, set to music, that companies could

    give to clients on a USB Flash Drive, or download from their websites. C++ under Windows,

    developed under Microsoft Visual Studio (MVS).

For software testing purposes I built two 'Schiz' machines, able to be rapidly switched to any

    given OS and any given service pack level. They currently support everything from MS-DOS

    2.11 through to Vista and Windows 7, and all modern Linux distributions. They also allow me

    to test websites under all browser types and versions.

President, Digital Design Ltd. (NZ registered company)

    Oct 1991 to Apr 2005

I developed HeliNav, a new navigation system for helicopters and tiltrotor aircraft such as

    the Bell/Boeing V-22 and Bell/Augusta 609. The software was written in C++. It dynamically computed - in flight - the routes and all obstacle clearance requirements, using the GPS position of the aircraft, Digital Terrain Models (DTMs), and obstacle databases.

At the time it was described by the FAA as the most comprehensive and complete system

    that they had seen to date. It culminated in an invitation to Washington DC by the FAA, where I put on presentations to FAA, NASA, and various industrial groups in 1996.

Being a New Zealand registered company I was unable to secure funding, and the project


Developed a number of downloadable applications for PCs, sold over the internet. This

    included Time Zones for PCs?, Remote Control for PCs, and The Metric Conversion


Time Zones for PCs? allowed individuals and businesses to see the CORRECT local time

    anywhere in the world (there are around 252 individual time zones in the world, and there are

    changes to the various daylight saving rules around the world almost every week - so it is not

    trivial if it is done properly). It also allowed people to plan ahead and coordinate times for

    international conference calls.

    For a number of year it sold reasonably well, with customers including Boeing, MasterCard Europe, E! Entertainment Television, Raytheon, and even the US Strategic Command.

    The work not only involved the products themselves, but the websites, marketing, and all the supporting internet infrastructure including 3 servers running Linux and Apache.

I also developed the entire product sale / download / registration / product update software

    that ran on the servers (C++ running under Linux).

    Rather than being sold outright as a product, because of the frequent data changes Time Zones for PCs? was sold on an annual subscription basis. It was probably one of the first of

    what is now known as SaaS (software as a service).

Assistant Navigation Services Specialist, Navigation Services Unit,

    Airways Corporation of New Zealand Ltd.

    Feb 1990 to Oct 1991
