Rockstar🎓
Top SchoolDavid Gräff is a machine learning engineer and seasoned C++ software architect with 17 years of experience building embedded systems, IoT solutions, and cloud-connected microservices from Switzerland. He blends low-level expertise—MCU and SoC development, Linux internals, Buildroot, kernel modules—with modern memory-safe practices, having introduced Rust components for networking and security on both device and cloud targets. At Leica Geosystems he delivered C++/Rust features for LiDAR surveillance and automated test-and-release pipelines, and he now works on ML edge computing and microservice architectures. An active open-source contributor, his refinements to projects like Eclipse Wakaama and OpenHantek show a pragmatic focus on correctness, packaging, and protocol robustness, while his work on moodlight and ArtNet in ethersex highlights a creative side in embedded IoT. He’s a community-minded developer who participates in hackathons and maintains pet projects such as a C++23 async mDNS library, demonstrating continuous learning across AI, edge ML, and systems software.
