San Francisco, California, United States
Summary
🤩
Rockstar🎓
Top SchoolKarim Naaji is a graphics software engineer with 12 years of experience building high-performance rendering systems for games, maps, and cloud services. Currently at Snap, he architects GPU-heavy, high-throughput rendering pipelines and texture-compression tooling, and previously led major real-time and 3D features at Mapbox including globe/terrain and live renderer metrics. His background spans console engine work at Avalanche (D3D12 performance and dynamic resolution) to open-source map renderers like Tangram and Mapbox GL where he made notable contributions to text and line rendering across WebGL and OpenGL ES. Comfortable across low-level GPU APIs, shading, and systems optimization, Karim pairs deep engine expertise with product-facing prototyping and cross-team collaboration. He also has a track record of improving developer workflows and performance visibility—introducing automated shader reduction and live metrics—and a knack for bridging designer intent with efficient graphics implementations.
