Notes on GIS and AI.

I work with organizations across disaster response, humanitarian operations, government, and the private sector — building mapping infrastructure, data pipelines, and operational tools that help people make decisions under pressure.

AI changed the math on custom GIS development. Tools that used to require a specialist — the ArcGIS JavaScript SDK, Python automation, full-stack mapping apps — are now accessible to anyone who can describe what they need. I document what I’m learning in real time, with working examples.
