Greg Turner
I build AI systems that make it to production.
Thirty years shipping software for Australian healthcare, government, banking and industry. Now designing and delivering the AI layer on top of it, from retrieval systems and agent workflows to the integration work that makes them usable inside a real organisation.

What I Do
One senior engineer, from architecture through to the code that ships.
Most AI work stalls somewhere between the demo and the day job. The model works, then nobody can get it past privacy, integration, cost or the people who have to use it. That gap is the work.
AI Systems
Retrieval augmented generation over your own content, LLM features inside existing products, agent workflows, and the evaluation and guardrails that make them safe to turn on.
- RAG pipelines and knowledge indexing
- LLM integration into live products
- Agent and workflow automation
- Evaluation, guardrails, cost control
Architecture
Where the AI has to meet systems that already exist. Integration across REST, SOAP, message queues and legacy platforms, identity and access, cloud design that survives an audit.
- Solution and cloud architecture (TOGAF)
- API and legacy system integration
- Identity federation, SAML, IAM
- AWS, Azure, GCP, Kubernetes
Delivery
You get me, not a team of juniors with an account manager in front of them. Senior-only delivery, accelerated by agentic tooling, inside your review and quality standards.
- Full stack and mobile build
- Agentic development at production quality
- CI/CD, infrastructure as code
- Contract or fixed scope
Selected Work
Systems that went live, and what they had to survive.
Seven engagements from the last decade. Each one shipped into production and, in most cases, is still running.

About
Thirty years of shipping, and no layer between you and the person building it.
I started as an analyst programmer in 1993 and never stopped writing code. Along the way I picked up the architecture side, a TOGAF practitioner qualification, an MBA and an AWS Solutions Architect certification, but the reason clients keep calling is that I still build the thing.
That combination is the point. Most AI engagements split into a consultancy that produces a recommendation and a delivery team that has to make it real, and the translation loss between them is where budgets go. I do both, which means the architecture is written by someone who knows what it costs to implement.
The work has mostly been in places where getting it wrong matters: Queensland Health clinical systems, Medicare claims processing, banking, the ATO, university identity infrastructure. Regulated environments teach you that a system is not finished when it works, it is finished when it survives an audit, an outage and the people who have to use it every day.
I'm based in Brisbane and work with clients across Australia and internationally.
Working Together
Two ways this usually starts.
Option One
Contract Engagement
You have a team and a roadmap, and you need a senior engineer who can architect and build without a ramp-up period. Typically three to six months, day rate, on site in Brisbane or remote anywhere in Australia.
- AI, architecture or full stack delivery
- Direct or through your preferred agency
- Own company, PI and public liability cover
- Available now
Option Two
Build Something
You have a defined thing you need built: an AI feature inside an existing product, a mobile app, an integration between two systems that refuse to talk. Fixed scope, fixed price, delivered end to end.
- AI and RAG features for existing products
- iOS and Android applications
- System integration and API work
- Quoted up front, no hourly surprises
