Cartographer: Heavy duty geospatial dashboards built for raw speed.

Rendering millions of real-estate data points in-browser, powered by edge serverless APIs and Neon Postgres. Seamlessly interactive regional insights.

The Challenge The client's previous visualization layer completely locked up the browser tab out-of-memory when rendering more than 10,000 mapping polygons. It needed a completely re-engineered data pipeline to make regional insights actually interactive.

Implementation

Serverless product engineering focused on raw speed.

Next.js App RouterUsed React Server Components explicitly to push heavy data-massaging compute onto Vercel edge functions instead of the client machine.
Neon Postgres & PostGISMigrated the traditional DB into serverless Neon Postgres running PostGIS, utilizing highly optimized spatial indices.
Mapbox GL & Deck.glImplemented WebGL-accelerated 2D and 3D data overlays rendering seamlessly at 60fps across vast dynamic viewport changes.
Vercel Edge CachingAggressively cached spatial vector tiles on Vercel's Edge network, reducing load times by an order of magnitude for repeated views.
