Summary
🤩
Rockstar🎓
Top SchoolPer Gantelius is a Stockholm-based software engineer with 13+ years of experience blending computational mathematics, sound engineering and game development into pragmatic software and design solutions. As a long-time freelancer and former game dev at EA and Iron Monkey, he ships work across the stack—from embedded and real-time systems to frontend UIs and 2D/3D graphics—often with a focus on DSP and audio. He contributes to notable open-source tooling, including enhancing the fSpy camera-matching app and its Blender importer, showing an eye for both UX and compatibility across complex platforms. Equally at home sketching visual concepts as crafting low-level code, he thrives on projects that mix technical rigour with creative experimentation. Always curious, he looks for collaborations that involve “weird” ideas or unusual technical challenges.
