Point Maps April 2016
Custom tile server for rendering millions of points on a map efficiently.
I wrote this as a learning exercise for dealing with huge amounts of data on a map.
The points are stored in Cassandra, where they are clustered by their tile coordinates at a predefined map zoom level. When a tile is requested, the tile server can then quickly fetch the correct points. The points are then rendered onto the tile in a way that looks nice but is very performant. The tile server also caches the tiles on disk.

Mapper August 2015
Web app for quickly plotting markers, polylines, polygons, heatmaps, etc. on a map.
Got geocoordinates but don't know how to see them quickly? Just paste them into Mapper! Doesn't matter if it's comma-separated, whitespace-separated, or something else. You can add multiple datasets and each one can be configured to plot different symbols or styles. Once you're happy with the visualization, it even has a button that gives you a link for sharing.
