Brisbane · Available for the right engagement

AI is moving fast.
Useful systems
still have to ship.

I embed in important operational problems and carry them from discovery through working systems, adoption and continuous improvement—drawing on more than 20 years of hands-on delivery.

01 / What I do

I’m most valuable where the problem matters, the path is unclear and a slide deck is not enough.

I can work inside an organisation for the full transformation journey—from observing how work really happens through architecture, hands-on implementation, integration, testing, adoption and continuous improvement. The goal is not to “add AI”. It is to improve how the organisation works.

02 / Capability

One operator.
Three kinds of leverage.

01

AI systems that can operate

  • Agent and MCP architecture
  • RAG and grounded knowledge
  • Evaluation and structured outputs
  • Permissions, audit and human hand-off
02

Software that survives reality

  • Mobile and native products
  • Cloud APIs and integrations
  • Offline-first and recovery design
  • Testing, CI/CD and release
03

Decisions that improve the business

  • Opportunity and workflow mapping
  • Product and commercial strategy
  • Targeted deep research
  • Build, buy, automate—or stop

03 / Selected evidence

Built across the stack.
Judged by the outcome.

Operational transformation, automation and enterprise delivery—labelled by their real state.

04 / AI-assisted, human-accountable

I use AI as leverage—not as authorship theatre.

Direction

I own the problem framing, product judgement, architecture and trade-offs.

Acceleration

AI agents help research, explore, implement, test and document at greater speed.

Accountability

Evidence, review, safety boundaries and the final result remain my responsibility.
