Rockstar🎓
Top SchoolDarafei Praliaskouski is a geospatial software founder and engineer with 18 years of experience building maps, spatial databases and analytics products. He leads Maumap and drives product at Kontur while serving on the PostGIS steering committee, contributing performance and algorithm improvements to one of the most important spatial extensions for PostgreSQL. His hands-on work spans OpenStreetMap, MAPS.ME and even in-game mapping for World of Tanks, blending deep PostGIS/PostgreSQL expertise with cartographic rendering and aerial imagery analysis. Known for shipping pragmatic fixes (from GiST indexing and k-means to weight-aware geometric median) and for making large-scale geodata pipelines robust, he bridges open-source stewardship with commercial product delivery from Batumi. Notably, he also built rapid disaster mapping tooling and a global population dataset, showing a consistent focus on turning messy spatial data into actionable insights.
