One more cool 🇺🇦 Ukrainian 🇺🇦 dev: https://github.com/mourner

I'm a software engineer. I created Leaflet, the number one library for interactive web maps, and maintain 40+ other open source projects with a focus on algorithms, computational geometry and data visualization. I'm building the future of maps at Mapbox. Here are a few of my best tech articles: https://agafonkin.com

I looked at some of his projects:

(project name - stars - short description)
Leaflet - 45k - The number one JavaScript library for interactive maps.
Mapbox GL JS - 12k - JavaScript/WebGL vector maps library.
pixelmatch - 6.9k - The fastest and smallest pixel-level image comparison library.
suncalc - 3.4k - Tiny library for calculating sun/moon positions and phases.
rbush - 2.8k - Fast dynamic R-tree-based 2D spatial index.
delaunator - 2.6k - The fastest JS Delaunay triangulation library for 2D points.
earcut - 2.6k - The fastest and smallest JS polygon triangulation library.
supercluster - 2.3k - Fast geospatial point clustering library.
geojson-vt - 2k - Fast tile-based geospatial index for GeoJSON data.
mapbox-gl-native - 4.5k - OpenGL-based vector maps rendering engine (archived).

OMG, that's insane 🤯
