Hospital Accessibility Analysis

This is the most technically ambitious thing I've built during my independent study. It streams live Overture Maps GeoParquet data straight from AWS S3 — rather than working from a downloaded, aging extract — and combines it with the U.S. Census API in real time to analyze how healthcare access lines up against demographics.

Illinois-focused, not "national"

I want to be straightforward about scope here: the intent was always Illinois. The dashboard shows data for other states too, but that's incidental — Overture Maps and Census data are both national datasets, and I haven't filtered them down. It wasn't a deliberate design choice to go national, and I'd rather say that plainly than oversell it.

How it's held up

I posted this on LinkedIn without expecting much, and it's gotten real, specific feedback from people in the field — a GIS data consultant flagged the clustering technique as worth borrowing, and a startup founder told me it directly shaped ideas for his own product. That kind of validation matters more to me than any metric I could put on the dashboard itself.
