Summary
👤
Senior🎓
Top SchoolJohnnie Hård is a Stockholm-based full-stack developer with 11 years of experience building data-intensive web applications, particularly in geospatial and hydrological domains. He designs and implements end-to-end systems—from TB-scale DEM preprocessing pipelines and high-throughput Node/C++ backends to interactive React frontends with D3 and mapbox-gl—while leveraging PostGIS, vector tiles and Redis for efficient spatial delivery. Comfortable across languages and stacks (Node.js, TypeScript, Python, Rust) and containerized deployments, he’s repeatedly architected solutions that translate complex geospatial analysis into usable tools for government and commercial clients. A collaborative team player, he actively improves processes and state management (XState) to make heavy-data workflows more reliable and user-friendly. His academic background in geomatics gives him uncommon depth in spatial analysis, enabling him to bridge domain science and scalable engineering.
