Summary
👤
Senior🎓
Top SchoolDusan Bosnjak is a Lead Software Engineer in San Francisco with 12 years building high-performance, web-centric applications that bridge front-end engineering and real-time 3D graphics. He specializes in React, TypeScript, Node.js and WebGL, and has optimized viewers to render multi-million-polygon BIM and Revit scenes at interactive frame rates by reducing draw calls, batching geometry, and moving work to GPU compute. A long-time 3D artist with a master’s in architecture, Dusan brings design-led thinking to technical problems—authoring mesh preprocessing pipelines, BVH-accelerated interaction, and custom geometry tooling for complex AEC workflows. He’s an active contributor to the widely used three.js library, adding renderer callbacks and NURBS support across loaders, which reflects both deep geometry knowledge and influence in the web 3D ecosystem. Comfortable across the stack and containerized infrastructure, he’s known for turning computational geometry and visualization challenges into practical, production-ready systems.
