06 · About

Finance first. Then data. Then AI.

Ten years across enterprise, government, mining and Australian businesses. I started in finance, operations and management control — which is why I build systems that answer business questions, not just run. Today I combine hands-on engineering with end-to-end ownership, and I’m doing a PhD in Computing at Curtin on machine learning for predictive maintenance and intelligent industrial systems.

07 · Questions

Before you book.

Do you work remotely, outside Australia?

Yes. I’m based in Perth (AWST) and work with teams across Australia and overseas, in English or Spanish. We agree overlap hours for calls; the work itself runs asynchronously.

What does a first project look like?

Usually a one-week Data Health Check or a small pilot with one measurable outcome. You see working results early, and decide the next step with real numbers.

How do you price?

Fixed scope per stage, quoted after a 20-minute call — so you know the cost before anything starts. Ongoing support is a monthly arrangement.

Our data is a mess. Is that a problem?

That’s the normal starting point. At Ready Chef Go I reconciled 10+ years of history across 20+ source tables before automating anything.

Which tools do you use?

Yours first — Excel, SharePoint, Power BI, MYOB, BigQuery, Databricks, Fabric, AWS, Azure or GCP. Open-source where it saves you money, never lock-in for its own sake.

Can you sign an NDA and work inside our environment?

Yes. I work in your tenancy with least-privilege access, and nothing leaves it unless we agree. Happy to sign your NDA before we look at any data.

Do you build websites?

Through KarrotsKode, the platform I built — that’s where the 145 designs above come from. My own work for clients is data, automation and AI.
