Some kids want to work in emergency services. I wanted to be a programmer.

Writing my first game in primary school but finding high school academics boring, I left school to chase a dream. I entered the exciting world of writing freight logistics and accounting software development.

In the 90’s, I immersed myself in code, architecture, and design patterns.

In the new millennium, I lead teams in Australia, Europe and Asia. During this time I leveraged code-generation tools and architecture skills to turn a failing IT project into a company divestiture worth $30M, 18 months later.

Searching for life balance, I found connection in dance (Zouk, Bachata, and West Coast Swing) and spiritual practices through Yoga, Sound Baths and Kirtan.

In the 2010s I worked with technology startups including a prominent ethical hacker platform, I pursued my interest in code generation, content creation and marketing.

 In 2022, with decades of experience in code generation and marketing, I discovered GPT-3/ChatGPT and prompt engineering and saw the end of traditional coding.  Today, 95% of my code is generated via LLM and AI automation is in every facet of my business workflows.
