Résumé of Ralph Hosking

Software Developer at TIM Technologies working with energy, environmental, signage, telecommunications and other devices. Generating customer invoices for telephone and electricity consumers. Other projects include online food ordering and associated back-end, merchant terminal and phone apps.

I have designed, created, or supported all aspects of these systems including CRM, databases, websites, invoicing, reporting, alerting, IoT endpoints, machine-to-machine communication, web services and APIs, phone apps, security.


I have worked in the software development industry since joining the Software Development Centre of BS Microcomp in Melbourne. After ten months I was assigned to the Japanese project culminating in four weeks in Tokyo. The OS/2 PM port saw me spend three or four weeks in Sydney. A year later the company was downsized and five of us were transferred to Luxembourg for one year, I stayed ten.

After ten years with DR-one I joined Odyssey Advanced Financial Solutions as programmer, and later development manager, working on MIRAGEcrm private banking application providing Microsoft Windows GUI access to AS/400-based DES-encrypted data.

After three years I returned to Australia and worked as an independent software developer before starting TIM Technologies Pty Limited.

During my Luxembourg-based period I spent time in Australia, Belgium, Netherlands, Singapore, Sweden, Switzerland, and the UK working with customers and suppliers.


There is much to cover here, I will just hit the highlights. The 'Career summary' section covers technologies with which I have spent most time.
