Resume

Geospatial data engineer and full-stack developer, building everything from cloud-native data pipelines to the TypeScript, NodeJS and React applications that put that data to work.

My full career history, education and certifications are on LinkedIn. This page focuses on the technology stack and a selection of reference projects.


Technology

The stack favours open standards, cloud-native formats, and reproducible infrastructure, and it spans the full stack: from Terraform-provisioned infrastructure and containerised data pipelines up to TypeScript and NodeJS services and React frontends. The engineering approach is deliberately pragmatic: technologies are selected not only for how well they serve the data and decision-making process, but also for how they reduce dependency on proprietary ecosystems.

Where a product calls for it, that means a lean full-stack application: a typed API in front of the data and a responsive React interface on top. Where it doesn't, the same data is served as lightweight, standalone applications with minimal backend requirements. Either way, the architecture stays cost-efficient, portable, and resilient, creating room for innovation that isn't constrained by the strategic decisions or lock-in models of software vendors.

The Technologies page lays out the principles behind these choices in more depth.
