20M+ Spatial Data Architecture &

20M+ Spatial Data Architecture & Web Mapping Performance Reworked a GIS data pipeline after the existing map architecture could no longer handle 20M+ spatial features effectively. I redesigned the storage, map-service and front-end access layers around PostgreSQL/PostGIS, GeoServer and WMS, covering data management, service publishing, layer rendering, feature queries and spatial analysis. I also isolated GIS preprocessing, analysis and rendering behind clear interfaces so regular front-end and back-end developers could work against stable contracts without depending on GIS internals.
