Enterprise GIS platform engineer.
The whole platform. One engineer.

// ex-Esri · ArcGIS Enterprise on AWS & Azure · Brisbane, AU

I architect, deploy, operate — and extend — enterprise GIS platforms end to end. Most people own one link in that chain. I own the whole loop: from the data model, through cloud deployment and go-live, into day-to-day operations, and down to the custom code that pushes the platform past what it does out of the box.

Right now that means keeping a global energy company's GIS and data platforms — ArcGIS, FME, SQL Server, Oracle — evergreen, secure and reliable for the business and its integrations: planning and running the upgrade, patching and modernisation programs, and leading an offshore team as the technical SME. Across a fleet of dozens of servers, the answer isn't more hands — it's automation: pipelines and self-healing that detect and resolve issues before they page anyone. Operations, done intelligently.

the closed loop

Five stages. Owned end to end, by one engineer.

A platform doesn't fail at any single stage — it fails in the seams between them: the architecture that ops can't run, the deployment nobody can extend. I own every seam.

[energy] platform-ops

Keeping the GIS & data platform evergreen — global energy company

Technical SME for enterprise GIS operations: keeping ArcGIS, FME, SQL Server and Oracle healthy so the business — and every integration hanging off them — keeps running. Plan and deliver the evergreen upgrade, patching and security programs, and lead an offshore team to execute them. Across dozens of servers I automate the repeatable work — pipelines and self-healing that detect and resolve issues automatically, not one box at a time.

Notes from the field.

I write up the things I hit in production — GIS tooling, automation, cloud and the occasional Linux yak-shave. Selected posts:

about

From Esri's labs to running the platform.

I started in geospatial at Esri China — implementing and tuning the ArcGIS for Server suite, building custom solutions and training clients (recognised as Outstanding Employee, with several Technical Innovation prizes).

In Australia I've worked across the consulting and engineering spectrum — Geosolutions Architect at AAM, Consultant at Esri Australia, Senior GIS Developer at NGIS, and now enterprise GIS operations at a global energy company — where I'm the technical SME keeping ArcGIS, FME, SQL Server and Oracle evergreen and secure, planning the upgrade and modernisation programs, and leading an offshore team to deliver them. Having sat on both the vendor and client side, I translate between business need and technical reality — and I write the code as readily as I draw the architecture.
