Hi! I'm Volodymyr Agafonkin.

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 performance. I'm building the future of maps at Mapbox.

I'm a musician. I write songs, play guitar and sing in Obiymy Doschu. If you like beautiful, evocative, multilayered rock music with string arrangements, check out our last album.

I'm a father to beautiful 9-year-old twin girls, I'm happily married and live in Kyiv, Ukraine. I love baking, photography, strength training, martial arts, reading, and exploring quiet parks. You can find tidbits of my life on X (Twitter), Instagram and Facebook.

Here are a few of my best articles:

• Reimagining projections for the interactive maps era
• How I built a wind map with WebGL
• A dive into spatial search algorithms
• MARTINI: Real-Time Terrain Mesh Generator
• Rendering big geodata on the fly with GeoJSON-VT
• Fast geodesic approximations with Cheap Ruler
• Clustering millions of points on a map with Supercluster
• A web map from scratch
• Kinematics of reverse-angle parking
• Introducing heatmaps in Mapbox GL
• A new algorithm for finding a visual center of a polygon
• Where Kyiv winters as snowy as I remember as a kid?
• How to give awesome public talks
