Rockstar🎓
Top SchoolStepan Kuzmin is a Senior Software Engineer and GIS specialist based in Helsinki with 14 years of experience building geospatial systems and interactive map UIs. Currently at Mapbox, he blends front-end craftsmanship on high-profile projects like mapbox-gl-js with backend and database expertise demonstrated in tile server work for MapLibre's martin. His background spans hands-on GIS architecture, seismic monitoring software, and leading engineering teams at Yandex.Taxi, where he combined technical direction with hiring and mentorship. Stepan is comfortable across the stack—from WebGL-powered map interfaces to PostGIS-backed tile services—and often solves problems at the intersection of cartography, performance, and user experience. He holds a master’s in applied geoinformatics and brings a rare depth in both domain science (geophysics) and production-grade geospatial engineering.
