GIS agents & reusable skills

Geographic expertise, made reusable.

I develop workflows for inspecting spatial data, building map applications, and checking results. Hermes GIS Skills brings that approach into a versioned library for AI agents.

Practical AI workflows

From information to useful work.

Research summaries, scheduled briefings, and monitoring connected to a person’s working context. I build around clear sources, reviewable outputs, and human judgment.
