The story

Scroll through problem, approach, and outcome.

Problem

Geospatial data lived in scattered files with no consistent schema, making it slow and risky to serve to web and analytics applications.

Approach

Designed a normalised PostGIS schema with validated geometries and spatial indexes, wrote ETL to load and clean vector data with GeoPandas, and built a FastAPI service exposing documented vector and tile endpoints — schemas optimised together with web developers.

Outcome

Delivered a reliable spatial backend with sub-second queries and a documented API, giving the web team a single trustworthy source for map data.
