Senior🎓
Top SchoolDavid Geldreich is a senior 3D developer with 14+ years of experience specializing in computer vision, real-time 3D graphics (OpenGL/ES, Metal), VR/AR, and high-performance ML pipelines across macOS, iOS, Windows and Linux. He blends low-level C++/ObjC++ mastery, GPGPU work (CUDA, OpenCL, Metal) and SIMD optimizations (AVX, ARM Neon) to port and accelerate complex media and plugin stacks—recently migrating DaVinci Resolve plugins between Metal and CUDA and porting a 3D engine from OpenGL to Metal at TomTom. A seasoned freelancer and contributor to open-source projects like deepdetect, he has practical cross-platform experience fixing Windows portability issues and improving backend HTTP/file handling in C++14 projects. His background spans research roles at INRIA and co-founding Realviz, giving him a rare mix of academic rigor and product-focused engineering. Based in Antibes, France, he routinely combines cloud tooling (AWS/GCP) with on-device inference (TensorRT, PyTorch, TensorFlow) to deliver performant ML-infused visual applications. Colleagues rely on him for pragmatic performance tuning and bridging research-grade algorithms to production multimedia software.
