I love making open source libraries related to maps & spatial analysis.

I've written a bunch of my own libraries such as

  • point-in-polygon-hao
    • A very fast and reliable module for point-in-polygon checks
  • sweepline-intersections
    • A very fast and small module for detecting intersections between polygons and polylines
  • Leaflet.SvgShapeMarkers
    • Provides additional SVG markers for leafletJS

I also contribute to a range of larger projects such as

  • TurfJS
    • Designed and developed the documentation. Implemented various modules. Provided various bug support.
  • LeafletJS
    • Occassion PR's for bug fixes. Writing and contributing to various plugins.
